I have a ton of respect for whoever sticks to the traditional vi! Not promising anything but this may have bumped the priority of supporting ^Z slightly in my TODO list :)
Also useful for jumping back and forth between e.g. multiple repl sessions (the re.pl on the top left is a readline frontend wired up over a socket to an p3rl.org/Eval::WithLexicals instance running inside the server I was debugging there).
Being able to do e.g. %Task to resume the lib/.../Task.pm editor is -really- nice once you have that many editors open, though I try and stick to about 5 per xterm normally so %- %+ %<digit> would absolutely be enough to get started with.
