Starting with public beta 5, DEVONthink offers the possibility to save any file from any application directly to the global inbox. No more saving to the Desktop and importing later.
First make sure that this function is enabled. Choose Help > Install Add-Ons, check ‘Global Inbox in Save Dialogs’ and click ‘Install’. This inserts a shortcut to the global inbox into the Finder’s sidebar. To save a document to DEVONthink now, look for the ‘Inbox’ item in the sidebar of the save dialog and select it as the location of choice. This even works when DEVONthink is not open, the document will be imported when you open the application the next time.
