I've been looking for a simple mod that will check for range and line of sight to group members, and either fade out the ones that are out of casting range or add a smiley or something next to the ones that are still in range.  I would like a mod that works with the default group windows (if possible) and does only the range/los checking, nothing else, so that it doesn't break every time a new patch goes online.  I realize that some of the ui mods out there are supposed to have this as an added feature, but I can't stand the grid and square looks, Pure doesn't have that feature added yet, and Streamlined Unit Frames and Clean Unit Frames both seem to have some bugs.  So, what I was wondering was if anyone could direct me to an addon that does what I'm looking for or if anyone would be interested in tackling this project.  My other option would be to try this myself if someone can direct me to a good guide for a newbie for how to make mods for Warhammer.  Thanks in advance for any information anyone can provide.

I haven't looked at the API since last december ish... I don't think that it supports a "range" function for script use. The one that tells you on screen "Not in range" isn't external from what I can tell... otherwise, right now it'd be like on a timer, ticking on your target, getting the range... and it'd increase the amount of CPU cycles your addons are using already...

A lot of the addon's that i've seen, don't work well as a large group, but when you load them individually or like 5 or so at a time it's fine. If you have a really beefy machine you're probably fine, but the large majority of the players probably aren't running high-end machines, and couldn't handle the graphics load, lag, plus all the addon chatter going on...
