If you are after a stylish user interface that just looks damn good try installing
DaimonUi. If you are in, or accessing, the US client then use the 4.0.1 version - it will work just fine. Or, if you want a slightly more minimal one try looking at
MyUi (Yes, yes, it is partly mine) which allows you to select a few options.
For warden gambits - and plugins
only work with the US client - try... *looks around* well... there were a couple on Beta but I can't seem to find them. I haven't got a warden so never tried them, but WardenEase seemed a good one. Hopefully it will get uploaded soon. Edit: Or try
WardenTrainerLite Now with a video review!
