Broadcast mode sends keystrokes from the active terminal to all other
connected sessions simultaneously. Useful for applying the same
commands across multiple servers.
- Toggle via Ctrl+Shift+B keyboard shortcut or broadcast button in tab bar
- Visual indicator: broadcast button pulses red when active
- Only sends to sessions in 'connected' state
- Notification on toggle
- State stored in app state object
Replaces the basic find bar with a polished overlay that matches the
terminal-search CSS. Features:
- Case sensitivity toggle (Aa button)
- Regular expression toggle (.* button)
- Match status indicator (found/no matches)
- Smooth entrance/exit animation
- Clears search decorations on close
- Re-focuses existing bar if already open
Sessions configured with auto-reconnect will automatically attempt to
re-establish the connection when unexpectedly disconnected. Uses
exponential backoff (1s, 2s, 4s, 8s... up to 30s) with a configurable
maximum number of attempts (default 5).
- New SessionReconnecting state with pulsing indicator in tab bar
- SSH and Telnet profiles gain autoReconnect and maxReconnectTries fields
- RAW protocol already had autoReconnect; now uses the shared mechanism
- CancelReconnect API to abort in-progress reconnection
- Frontend shows reconnect attempt notifications
- Profile editor exposes toggle and max attempts in Advanced/Reconnection
Removed conflicting padding from layout.css and terminal.css that
stacked to ~11px. Now a single 3px top+left padding is applied
directly on the .xterm element, keeping text visible and tidy.
Added MutationObserver in utils.js that sets autocapitalize=none,
autocorrect=off, and spellcheck=false on every input and textarea,
including dynamically created ones (profile editor, SFTP modals, etc).
Changed from flex-sibling layout (broken by absolute-positioned terminal
container) to an overlay approach: the SFTP panel is now position:absolute
on the right edge with a drop shadow, sliding over the terminal. The
resize handle is embedded inside the panel at its left edge.
- Added 📁 folder icon button on SSH tabs to toggle the SFTP file browser
- Button appears on hover/active, styled consistently with the close button
- Removed conflicting Cmd+Shift+F shortcut (clashes with macOS find)
- Added platform-specific window options (Mac, Windows, Linux)
- Added F11 fullscreen toggle and Escape to exit fullscreen
- Cleaned up SFTP panel on session close
SFTP file browser:
- Created internal/sftpclient wrapping github.com/pkg/sftp for remote file
operations (list, stat, mkdir, remove, rename, download, upload, pwd)
- Integrated SFTP into session manager with lazy client creation per session
- Added API methods for all SFTP operations with native file dialogs
- Built SFTPBrowser frontend component — right-side resizable panel with
breadcrumb navigation, sorted file listing, context actions (download,
rename, delete), upload, new folder, and custom modal dialogs
- Toggle via Cmd+Shift+F on active SSH sessions
- Auto-refits terminal when panel opens/closes/resizes
- Panel cleaned up automatically when session closes
OpenSSH config import:
- Created internal/sshconfig parser for ~/.ssh/config Host blocks
- Converts to profiles with hostname, port, user, identity file,
ProxyJump (first hop), ForwardAgent, and Compression support
- Skips wildcard-only hosts and Match blocks
- Import button added to Settings > About tab
Automatic update checking:
- Created internal/updater querying GitHub Releases API
- Simple semver comparison, 10-second timeout
- Dev builds never trigger update prompts
- Check button added to Settings > About tab
Session Recording & Playback:
- Add recording package with asciicast v2 format writer and reader
- Recorder captures terminal I/O with timestamps from SSH and Telnet sessions
- Input and output events recorded via hooks in session manager callbacks
- Recording store manages .cast files in ~/Library/Application Support/NexusTerminal/recordings
- Recording browser modal lists all saved recordings with metadata
- Full playback viewer with embedded xterm.js terminal, progress scrubber,
play/pause/restart controls, and 0.5x-10x speed adjustment
- Recording indicator (pulsing red dot) shown on active tab during capture
- Keyboard shortcut Cmd+Shift+R to toggle recording on active session
- Tests for recording, store listing, deletion, and double-close safety
Encrypted Profile Export/Import:

New protocol type 'github' for browsing repositories via the GitHub REST API.
Creates a non-terminal panel showing repos grouped by owner/org, sorted by
last commit date (newest first), with search filtering and auto-refresh.
Backend:
- ProtocolGitHub constant and GitHubConfig/GitHubRepo model structs
- New internal/githubclient package (REST API, pagination, token validation)

Sidebar:
- Add -webkit-user-select: none to section headers (WebKit prefix)
- Fix class mismatches: sidebar-section-chevron → section-chevron,
sidebar-section-count → section-count, sidebar-section-list → sidebar-list
Terminal resize:
- Poll container dimensions after creation — retry fit every 50ms
until container has non-zero width/height (up to 20 attempts)
- Add flex: 1 and min-height: 0 to .xterm inside session-panel
so it participates in flex layout correctly
.gitignore:
- Comprehensive rewrite covering build output, Wails bindings,
frontend libs, IDE files, OS metadata, and application data
Theme:
- Replace all purple/blue-tinted backgrounds (#1a1a2e, #1f1f35, etc.)
with true neutral charcoal greys (#1c1c1c, #232323, #2a2a2a, etc.)
- Neutralise text colours (remove blue tint from secondary/tertiary)
- Update xterm.js theme and session overlay to match
Terminal resize:
- Add fitSession(sessionId) method for targeted terminal fitting
- Fire fit at 30ms, 150ms, and 500ms after 'connected' state event
- Ensures terminal fills container even when layout settles late
- Add pencil edit button on each sidebar profile item (visible on hover)
- Fire fitAddon.fit() multiple times after terminal creation (50/150/400ms)
to catch the panel finishing its CSS layout
- Re-fit terminal when session:state transitions to 'connected'
Layout:
- Add panel-container and session-panel CSS so workspace content
doesn't overlap sidebar
- Session panels use position: absolute to fill workspace area
- Workspace is now flex column for proper empty-state/panel stacking
Terminal:
- xterm.js overrides now target .session-panel in addition to
.terminal-container so terminal fills available space
- Added debounced window resize handler for terminal re-fit
Notifications:
- Rewrote Notifications class to emit .notification-* classes matching
the existing polished CSS (was emitting .toast-* with no CSS)
- Icon is now a small coloured circle badge instead of oversized SVG
Sidebar:
- Fixed class mismatches: sidebar-dot → protocol-indicator,
sidebar-item-sub → sidebar-item-host, sidebar-star → sidebar-item-star
- protocolColour() now returns proto-ssh etc. matching CSS selectors
Other:
- Replaced prompt() in tab rename with custom _inputPrompt modal
- Change ConnectSession/ConnectQuick to return SessionInfo (not string)
- Change UpdateProfile to return (Profile, error) for frontend use
- Make session connection asynchronous to avoid Wails event loop deadlock
- Implement event-based secret prompt (backend ↔ frontend via requestID)
- Add TestConnection API for TCP reachability checks with latency
- Add 'Save & Connect' button in profile editor
- Wire _testConnection to real backend TCP check
- Add btn-accent CSS for the green action button
Add cursor: pointer and -webkit-user-select: none to form section
headers so WebKit does not initiate text selection on the first click,
which was swallowing the toggle interaction.
- Moved main.go from cmd/app/ to project root (Wails convention)
- Makefile now resolves wails binary via GOPATH/bin fallback
- Updated wails/v2 dependency from v2.9.2 to v2.12.0
- Fixed preferences round-trip bug (store as single JSON blob)
- Fixed import strategy test (needs non-empty profile data)
- embed.go: embed index.html + all:src directly instead of all:dist,
so `go build` works without a prior npm build step
- index.html: add missing xterm.css vendor stylesheet link
- build.js: add buildDist() to assemble dist/ with index.html and the
full src/ tree; update required-file paths to match dist/ layout
- Add placeholder xterm lib stubs in src/js/lib/ and src/css/lib/ so
the app can start before `npm install` is run
- .gitignore: stop ignoring the lib placeholder files so they are
available on a fresh clone
