Switched from tmux to herdr a while back and the one thing I kept reaching for was choose-tree. So I wrote it as a plugin.
Collapsible tree of workspaces and tabs, tmux's jump keys (0–9, then M-a…), and a preview strip showing what's actually on each pane right now, one panel per tab on a workspace row, one per pane on a tab row.
Because herdr pushes events over its socket, the tree is live rather than a snapshot — close a tab elsewhere and it updates under you.
