menu bar icon for "Show Snapshots"

would come very much in useful!

Since this is embedded in the inspector, you can use the blue ā€˜iā€™ icon to toggle it on and off. Each of the inspector panes has their own button down at the bottom, so replicating all of those in the toolbar would lead to clutter. However you can use Ctrl-Opt-Cmd in conjunction with H, N J, M, and K to activate each of the sub-panes. This is easier to remember if you look at how they are laid out on the keyboard, so Snapshots would be Ctrl-Opt-Cmd-M, since it is second to last.
