uSSH

Live updates in Finder and Files
Remote folders now refresh on their own. A small signed helper, ussh-fsmonitor, runs on the host over the existing SSH connection and streams changes back; uSSH installs and upgrades it for you and verifies every copy against a key published in a DNSSEC signed DNS TXT record. It watches only the folders you have open, so a busy home directory costs nothing, and the extension keeps a feed alive briefly even when the app is closed. Resync Now really resyncs, deletions reach Finder, and root@ bookmarks can opt in.

Paste safety
Right-click paste, and a confirmation before any multi-line paste. A built-in rule set flags dangerous commands, and on Apple-silicon devices the on-device model reviews the clipboard and streams its verdict into the sheet, with a red Paste button when the risk is high. A quiet mode lets routine pastes through while still holding anything the model dislikes.

Find in scrollback
⌘F searches the scrollback of shell tabs and tmux panes alike, on Mac and iPad. In tmux it can escalate into the pane's full server-side history, and the local scrollback follows the pane's own history limit.

tmux across devices
Shared sessions get a size lock with ownership: the first device to lock a window keeps its size, others see a scaled view instead of fighting over the grid. Session names are per device, and closing a session's last window no longer disconnects you.

Selection
Option-drag block selection on the Mac for copying columns out of TUI panels. Shift-drag selects text even inside mouse-aware programs such as btop or tmux with mouse mode on.

Keys and trust
Passphrase-protected OpenSSH keys import directly. DNSSEC trust aot key rollovers the RFC 5011 way, so validation keeps workingacross the October rollover without an update, and the pre-connect terminal log narrates every DNSSEC and SSHFP step.

Symlinks are followed on the server, so linked folders such as /ookmarks mount read-only by defau…
