- 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.
Root cause: lipgloss Width(maxW) = content area inside border, border adds 2 chars extra.
- halfW was t.width/2, should be t.width/2-2 (reserve border per pane)
- innerW was maxW-4, should be maxW-2 (padding only, not border)
- Each pane total = maxW + 2 (content + border)
- 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)
Phase B — Tamagosh-inspired dual-pane file browser:
- Left pane: local filesystem (starts at /Users/swanadiva)
- Right pane: remote filesystem via SFTP
- Tab key switches active pane (green border = active)
- Local CWD indicator per pane
- File listing with dir/ file size display
- Filter mode with / key
- Copy files: C key copies from active pane to opposite pane
- Delete (D), mkdir (N on remote), Refresh (R)
- Esc to close
- File size formatting (B/KiB/MiB/GiB)
- Progress message during transfers
- StylePaneActive (green border) / StylePaneInactive (muted border)
- SFTPBrowserTab with remote directory browsing
- Open via Ctrl+F from host list
- Navigate dirs, filter with /, refresh with r
- Dir/icon display with file sizes
- Sort dirs first, then by name
