Button that collapses all headings (maybe also bullets)

When already using the mouse, it can be a slight diversion to press the hotkey for Fold all headings and lists then return to using the mouse. In these cases a button could be worth having, especially if this is needed regularly. Try checking out the Commander plugin. Another option that might be worth considering is programming a hotkey for a button on your mouse. See this request as well: Added hotkeys for Fold Headings and Fold Indents

Good luck!
