Sidebar like Mail’s Activity

Hello,

The Sidebar is only used for switching Databases, but needs to be open most of the time since it’s the only (or at least easiest) way to use the Global Inbox and the Trash (and all the global Smart Groups). But the Sidebar takes a lot of space, so that I have it closed most of the time, but then I can’t access the Trash and I keep opening and closing it.

I think it would be great if it could be handled like the Mail Activity in the Mail app or like the month overview in Calendar (at least in Split and Three Pane View in Widescreen mode): A little space at the bottom of the folders panel. The actual size could then be adjusted as needed by making it higher.

Thanks a lot.
