I'll never understand why anyone is against adding features that allow for more customization options. I think Warp is right that the PS3 release will prevent any mods from becoming "must-have." Once the PS3 version is released, the PC community will be the minority. There may be mods available for PC, but they will unlikely be available for PS3 unless officially released as DLC or something similar.

One thing I would like to see added is collectable themed frames, like in Chrono Cross. They could be obtained through quests and enabled through the configuration to provide different UI themes, like a jungle theme or whimsical ones with chocobos and moogles.
