emacs' discoverability has been quite terrible. A couple years back I wrote half of a package to do ascii art before I discovered artist-mode. And I had been using emacs for close to a decade by then. This year I discovered ace-window had hidden keybindings (C-x o then instead of choosing the window you want, type '?' to get the dispatch menu). Again, I've been using ace-window for about a decade. Adding a transient dispatch menu to Isearch would be great. I'd also suggest a more global keybinding for hidden dispatch menu (I suggest M-? for dispatch menus when using the minibuffer and ? for other modes).
