Add command support for the input box #7
Description
It could offer autocompletions for actions, like modern editors (Sublime, Atom, VSCode etc), for toggling filters etc.
Of course profile additions should take precedence, and commands should not override those.
Commands could either work with a trigger words, or without (because filters are just toggles, and unintuitive keywords would never be used or discovered). As long as filters have lower priority and visual separartion from for example remembered profiles, it shouldn't hurt.
