Revise confirmation popups

There are a couple of popups which should be manually closed otherwise they don’t go away. These include the popup when the project loads and the two on the photos below. Probably there are some more.

I wish that in the situations where these popups inform the user and don’t really require a confirmation, the new popups could be used instead (more popups!). I believe there is no reason to distract the user by making them press a button (except for the situations where it is really necessary).
