There are several things that I don't like having to look in menus to see what state they are in. For me, the top priorities would be grid 'absolute/shuffle state' and 'automation follows events' states. I have key commands for both, but I need to be able to quickly see which one I'm in.
It would be great if we could use the space to the right of the grid/shuffle/follow etc buttons for custom actions and their current states as well as common macros etc.
