Line Properties (& Others) dialogue should have an Apply button

Maybe this is already in the works, but for instance when working with lines the hook lengths sometimes are not known until related visually with the score. The thing is is there is only an OK and Cancel button on the dialogue box, so if you're visually doing this you have to change the settings, then press OK, then possibly you will need to go into the dialogue again to change to taste. It would be nice to have an Apply button on this and other dialogues like it. Then again I think I read on here that it was being entertained that these sort of settings might all end up in the Inspector in 3.0.
