I had some feedback on the designer some weeks ago, that it would be good to filter away closed databases in package explorer. This does already exists in Designer today, Kudros to Dan O’Connor that showed me this. (The icon has changed from 8.5.3 to Designer 9)
And uncheck Closed projects
Now your package explorer is much cleaner and you can find you databases alot faster.
The closed project does also show up directly in the menu so you easily can toggle it.
You can also use worksets here to get better filtering of databases and on disk projects
