T13: the right column's Git and Files switch, kept in settings; Files shows the shown session's folder as a tree, folders first, Git's marks on names from git status without optional locks, unreadable folders noted; a double press opens a folder, or a file in the system's app; it reloads when the session reports a folder, so at each prompt; a program without shell integration gets a line saying it reports no folder; header controls keep their presses from the header's double-press zoom
