Would be great if DEVONthink’s preview options
could be toggled via clicking them in the toolbar. Currently it’s just irritating that clicking a view mode doesn’t do anything.
(I know how to toggle them via Keyboard Maestro, but this doesn’t help when I use the mouse)
Toggled between what exactly?
Re-clicking any toolbar item should toggle.
Should toggle between what:
The view/edit pane showing or not showing?
The current and previous state?
The view/edit pane showing or not showing.
Why not just hit the appropriate toolbar button or shortcut?
Because I then first have to search the appropriate button and often fail in doing so 
Yeah that’s the menu. I was talking about the toolbar buttons
