Currently the resolution is not saved. This should be changed.

Hm... Currently the editor does not have any saved settings... Would need to implement that.

Or could we add startup parameters? At least for my uses that would work as well but other users might never know about such parameters

Some config saving should be implemented. I guess it won't be to hard...
