Right now the Casual Game interface is confusing with three tabs: Ranked Practice, Non-Ranked, and Custom. Also, there's no way to play on standard boards against the AI or without the timer. So here's the changes I'd like to make: Remove the Custom tab and put the Scenario Editor somewhere else like the Main Menu. Making and playing are different actions, and separating them should remind people to save their work before testing. Merge the Ranked and Non-Ranked lists into one list of standard boards, with current active Ranked and League boards in bold at the top of the list. Have a checkbox for whether you want a timed game or not, since casual games are mostly used for testing and practice. Have a button for "Load Custom..." with the name of the currently loaded custom board next to it. The list of players online should start with "[AI]". If the board uses your opponent's MP Party, the server matches you against the AI closest to your ELO. This option makes the "Is AI" checkbox in the Scenario Editor obsolete. After "[AI]" the list should show your online Friends in bold, then your non-friends.
I agree with points 3, 5, and 6. I like the separation of the ranked boards and the league boards. You can play scenarios with other people, just keep the "Is AI" off.
