Me, 800x if you mind.
Could message window be a bit wider? And what is this small ... something below and left? Message window could be enlarged with that width, I think it will be closer to original one then.
Got it. New size is almost ready. Tbh, I completed it on March, 26, but got one problem and stopped making it for some time. But tomorrow, I guess, I'll continue developing it.
p.s. What king of windows are you talking about? Is it small or big one?
As for me, it is better to have small window hidden, and big appears when I press F5.
