When I scan a sheaf of documents into “Imports,” and I double-click on one, it opens the document in the Devonthink window; but I cannot figure out how to go back to the “Imports” — i.e., the thumbnails of all of the files that I just imported — without quitting and restarting Devonthink.
There’s a Done button in the lower righthand corner of the window.
Press it and you’ll go back to the Imports.
