Most of the time I like to use Sublime Text with all locations enabled, so I always have a decent overview of what my team is doing:
However, sometimes I want to hide everything except one or two branches, to get a better idea of what I’ve been doing

What I’m really missing is an easily accessible, convenient “toggle all” button for visibility in the Locations panel.
I know there are the commands “Hide All Branches Except …” and “Show All Hidden Branches”, but for something I do relatively often it’s a bit of a pain to have to type a command.
Any time you have a list of items with checkboxes next to them, it’s intuitive to have a “check/uncheck all” button at the very top. Perhaps you could put it right next to the existing filter button?
