FR: Expand list of games for tall client window.

[alexfornuto]

Is your feature request related to a problem? Please describe.
When the client window is taller than it is wide, the list of games does not expand to the bottom, wasting space on the screen:

Describe the solution you'd like
I'd like the list of games to expand in this window form.

Describe alternatives you've considered
One could maximize the window to fit the screen, but that's not great for multi-taskers.
