Because I am trying to maximize screen space, I would like to turn off the sidebar, but I still need to switch between databases frequently. Is it (or could it be) possible to add a database selector to the toobar (see attached for a mock-up of what I would like to do)? It seems like a very simple thing; I just don’t know how to do it.
Thanks,

No, it’s not possible, but you could easily have a window open with a database in each.
You can also setup Workspaces (Go Menu) and switch databases with each Workspace option-command-number shortcut. Shouldn’t be too hard to write a script that executes the shortcut, and put the script in the Toolbar if clicking to switch is more convenient than a menu or shortcut.
… and if you have Sierra tabs active, selecting a database in the sidebar and choosing New Window from the contextual menu will open that database in a new tab. These settings are persistent if you quit and reopen DEVONthink later on.
That would be my preference as well. I still use the Sidebar, but I’ve pretty much stopped using Workspaces now that we have Sierra tabs.
I am missing something here, how do I activate Sierra tabs?
Go to the Dock preferences, change the setting for Prefer tabs when opening documents from the default of In Full Screen Only to Always.
Thanks Greg 
Thank you all for the suggestions! I just migrated to Sierra and had yet to discover Sierra tabs, so I’ll try that out. Thanks again!
