It would be nice to have a button to collapse all subs at once. I find over time I have progressively opened a ton of subs... so I would be a nice feature to close them all and get my head back focused on where I was working. I also noticed that after closing subs that they pop back open. I haven't had time yet to figure out when it happens, meaning after running, or saving or reopening. It would be nice if they stayed closed until opened.
