I have been toying with a “no title” chat window, but missing the close/minimize buttons, even though I could right-click and close them, just was getting annoying.
So I enabled the buttons again with a “no title” window I had made, but I was not happy with the way the title was showing.. like was being cut off.
I decided to make a compact “thin” title version of the chat windows that the title bar is only 10 pixels high. I have also refined the close/minimize buttons to compensate so it is a little easier to click. Everything seems to be working so far, so will do some further testing.
