I know Splork's been having a blast with MXP, and most the changes he's been making are pretty cool. However, on the topic of MXP, I have the following suggestion:
It would be nice if anything available in the prompt was an MXP option. ie. We can have both a configurable prompt and configurable MXP.
Reason I suggest this, there are lots and lots of things I'd like to program my client to keep track of for me that I don't really want to see in my prompt. ie. Dawnfire is pretty cool, but I don't want weather and time info in my prompt...
An option that would competely rock (but I dont' know how to do) would be to add spell data to MXP (Ok, I have an idea how). I've seen the cool little status bars that some players have in their clients and I think they're great. I've even heard tell of people who have status bars with buttons that let them quickly recast spells and think that's even better....
Would be a very helpful thing to add to the newbie section though.
