I would make the battle screen a little smaller (at least in the right side, the part with fight poke etc), I usually play with 800x600 resolution and I'm able to click only on the first 3 poke in my party.
Also add a link to the forum under the log out option.
Another nice thing would be adding a lot of new shortcuts. The way to do that could be adding a DAO style's shortcuts bar, where you can drag the shortcut bar and make it long as you wish. 5, 10, 15, 20 slot, you choose. So the "base" could be 5+arrow icon, then is up to you. Well, I don't even know if it's possible to do that, I'm just doing a suggestion.
