suggestion: select database in APP, not in settings

[secuder]

Sometimes it makes sense to switch the database: As you can not rely on a 100% complete database, you might have a look on the alternative database.
Or you want to contribute to both databases with a picture or a success information.

Switching to settings, selecting the other database and going back to the APP is much to inconvinient to do so.

Might be difficult to realize without disturbing or additional elements on the user interface :-/
