The loading bar should not be a separate window, but should be integrated withing the editor

The loading bar which appears on saving scripts etc, is very annoying. When you click save on a script, this loading bar pops up in front. I would request you to have the loading bar not as a separate window, but a window which is a part of the editor.

 

It's a locking operation, ergo not a background operation. It should pop up as it does to make it plainly clear why Unity is locked at present.
