Main problem is drag and drop from a maximize windows to another window(not maximized). I have a maximized nautilus window and i want to drag and drop a file into skype window. But as soon as i click on file, skype will hide under nautilus window. Also drag file on unity launcher does't work in ubuntu 14.04, specially when there are multiple window (for one launcher icon).
We can simulate this by disable the option "Raise on click" in compiz settings. But this option also create problem to raise the window. I think if we can configure that "Raise window on mouse up(left button) event" then drag and drop problem can be solve. I googled for a long time but no luck. I am almost sure, there is no option to do this.
I also didn't find any hints to do this. I am a developer, i can code. I need to know the point where to start. Can someone help me to find the way? Thanks in advance.
