Death to deadspace?

[GenesisRage]

with my custom UIs they get rid of all deadspace, but when i change settings to get rid of the title bar it creates deadspace where the titlebar once was.

ive tried having it move everything up to cover the space, but then it creates deadspace below the window, also im working with the mainchat window so i dont want to just change the size of the window itself (unless there is a way to do some math like size=x,y-19)
