You need to figure out a way to widdle that list down to people that you KNOW you want to track instead of tracking everyone in a list. You need a non-visible ignored list or something like that. There just can't be 250 toons engaged in your silly PvP stuff. :p
Yea I know. I haven't really done any optimizing of the list filters since I initially did them. There's TONS of room for that still. Like completely ignoring all npcs and such. All non essential pets. That kind of thing. I just haven't got around to it yet. I wanted to make absolutely sure the list functions were working as someone would expect tho. Just in case someone decided to take it to an extreme like that.

I was JUST considering another way of doing it actually, that's why I was asking about marking relevant targets and such. I might get rid of the "enemy" list completely and just have all RELEVANT targets in the target list, and set a timer for them for like 1 hour.

No reason they should still be in the list after that if you're doin your job right anyways. hehe Maybe robust up the part where you can select them by guild name and such. Because I have that in there. User tag input? Who knows. There's so many options with this it's crazy actually.

I don't want to move forward tho until I get a good idea of where I want to go from here. With your tabbed stuff and new save/load file system, I might just halt until that's all done.
