Remove / disable multiple inboxes

I‘d like to disable the multiple inboxes. Personally I only need a single inbox which is much more straight forward. It’s not a big deal on the Mac, but in DTTG sometimes I go to the global inbox and don’t find the item I just added on the Mac - until I notice that it was added to the inbox of the database.
This would especially be useful for users with only one database (like me).

Thank you for the suggestion, an upcoming release will revise the handling of the inboxes.
