Hi andras, that's an interesting idea, but I'm not sure if I understand completely.

Do you mean you want a way to rotate for example the "Right" view so that it was viewing in some other direction than from the right-hand side?

That seems like it could potentially be pretty confusing, because it would have that label of "Right" on it, but if you had rotated around somewhere else, you would actually not be getting the view looking from the right-hand side in it anymore... Those view labels would basically by lying then, they would say things like "Top", "Front", "Right", for views that were not Top, Front, and Right...

Also what if you moved your Right view to some other direction, but then later on you wanted to return to an exact Right view?

Maybe you would be interested in this plugin which gives an animated turntable rotation in the 3D view:
