Hello there and congratulation for this piece of great software!

My suggestion is to change the UI so that the shortcuts of available actions are displayed beside colored buttons as keyboard's function buttons (as seen from above) instead of in the bottom line of the window.

The bottom line of the window could be replaced by some sort of visual tooltip (like the ones seen in tv tournaments) that displays the percentage of winning of the player...

Thanks for listening and keep up the good work,
S.

PS: I know it's been already asked, but please implement on-line tournaments handling as soon as possible!
