Do we need so many tab pages in the message panel?

[Jenna]

Are there any experiences

I've used it, too since day one, no issues here.

Are there any objections against committing the patch ?

Not from my side.

No further comments,so I just committed the patch.
In "Settings -> Environment -> View" there is a new option, that allows the user to decide, whether it will be saved which tab is selected on perspective change.
