- Add Theme struct with 3 predefined themes (dark/light/druntime)
- Add Profile struct for named configuration profiles
- Add ErrorBanner with severity levels and auto-dismiss
- Add unit tests for theme, error banner, and models
- Update CHANGELOG.md and PROJECT_STATE.md
- M key enters rename mode with current name pre-filled
- Type new name, Enter to confirm, Esc to cancel
- renameItem: client.Rename() for remote, os.Rename() for local
- Clear cache + refresh after rename
- Footer updated: M:rename
- Filter mode allows M to pass through
- Clear dirCache before refresh after transfer/delete/mkdir
- Cache was stale: old entries returned instead of fresh data
- Filter mode: allow commands (c,d,n,r) and nav (↑↓,Tab) to pass through
- Filter mode no longer blocks transfer/delete/mkdir/pane-switch
- Delete: clear cache + program.Send() for re-render
- Mkdir: clear cache + program.Send() for re-render
- Added program *tea.Program to SFTPBrowserTab and Model
- SetProgram() allows goroutines to send messages to Bubble Tea
- After transfer: program.Send(sftpRefreshMsg{}) triggers re-render
- Model stores program reference, passes to SFTP tab on creation
- Progress bar: [████████░░░░] 67% 12.3MB/18.5MB
- progressWriter wraps io.Writer, reports bytes via callback
- Footer shows live progress during upload/download
- Auto-refresh destination pane after transfer completes
- Success message shown for 1 second before clearing
- Added dirCache map to sftpPane for caching directory listings
- Cache hit: instant navigation (no disk/network I/O)
- Cache miss: read from disk/SFTP, store in cache per path
- R key clears current directory cache and forces fresh read
- Significant speedup when navigating back to previously visited folders
- Default active pane changed from Remote to Local on SFTP init
- renderPane now takes maxH parameter for fixed border height
- paneStyle.Height(maxH) prevents border from shrinking/growing on scroll
- Stacked mode: maxH = t.height - 6; Side-by-side: t.height - 5
Stacked mode (<50 cols) now shows only the active pane (Local/Remote)
with a visual indicator bar. Tab switches between panes. Side-by-side
mode (>=50 cols) unchanged.
- NEW responsive.go: wrapFooter, adaptiveSidePad, clampWidth, truncateStr
- Footer auto-wraps to multi-line on narrow terminals (full labels preserved)
- Box width clamped to terminal width across all tabs
- Host/key/snippet rows truncated with ellipsis; compact format <35 cols
- SFTP panes stack vertically when terminal < 50 cols
- Tab bar truncates names on overflow
- Form contentW minimum lowered 50->30 for mobile
- Fixed: key_list_tab & snippet_list_tab dropped last data row (off-by-one bug)
