This is NOT a bug, but a feature request..
When working with frames, it can be very tricky to get the size/proportions and position of the frame exactly right.. it would be great to have an "apply" button so that the frame windows remains open and the changes can be seen directly, this could potentially save a fair amount of clicking....
The Apply button has been requested on many if not all dialogs in bug 37336. Not sure if we want to make this ticket a duplicate or change the other into a meta.
I strongly support this enhancement.
