Change Default Windowsize

[Sognar]

Is it Possible to change the default Windowsize (in Windowed mode) to something else?
The Default Size looks rather small on my 27" 1080p Monitors and i find my self resizing the Window everytime, which I find a little bit annoying.

I have the problem the other way around. The window is to big for my screen

Anyway it is on the internal TODO-list
