Problem / Steps to reproduce

What I want to implement for my project is some kind of input method like you have in vim for instance where you have a certain keybinding and then you have a colon at the bottom and you can enter and run a command. To my knowledge this should be possible with the execute action but there seems to be no option to not clear the screen before the action is run (it does work with the action "become" but then fzf gets closed). I think this would be a useful (and probably ease to implement?) option as it would open new more application-like use cases for fzf (I try to build an email client).
