Is it possible to have a toolbar button that is shown only when nothing is selected? In other words: if there's a selection, hide it ... kind of like the opposite of ´@hidenosel´.
TL;DR. My purpose for such a button would be to create a "VS Code this dir" button that opens the current dir in my editor. And I'd like to use the button in combination with my other buttons which uses ´@hidenosel:type=grp:My Coding Files´ and ´@hidenosel:dirs´ respectively. The end product would be just one, smart, if you will, "VS Code" button shown at any time, that operates differently depending on what's selected or not.)
