I had to start Creator with -tcs (temporary clean settings) a lot recently to debug different issues. And I also advice others to do so if they encounter problems that might be settings-related.

Unfortunately, every time you do so you have to dismiss the "Take a tour" dialog if you don't give the parameter -notour too.

Creating messageboxes without the users demand is bad behavior, and might create the opposite impression on new users - that Creator is user-unfriendly (which is not the case, fortunately).

I think it would be much better to have a prominent button on the welcome screen. (E.g. on the projects panel, which should be completely empty for a new user). Or any kind of other non-modal dialog.
