+
+Lists the daily kitty sessions that `~/.config/kitty/day_session.py` saves under `~/.local/share/kitty-sessions/<monday>/<day>.kitty-session` ([kitty daily sessions](/terminal/kitty#daily-sessions)). Entries are `<day>  <weekday>  week of <monday>  <n> tabs<TAB><session file>`, through `mtime-sort`. The preview parses the session file with an inline `python3` script (written without braces, which tv would treat as templates): each tab, then each window's cwd and the program it restores, with the last 6 lines of its saved scrollback in color.
