Popgroup is a mod I have used since...forever. It still works fine with all patches but the author no longer continues to write for it. It works really really well for healing classes, Paladins especially where you regularly buff party members.
Basically here is what it does:
_____________________________________________________________________
Pop Group is a simple utility that pops a list of your groupmates
under the cursor when you click a beneficial spell (buff, heal etc)
without a friendly target targetted.
Your name shows up under the cursor, so self casting is a double click.
The bars with the names are color coded for that player's health - green
is above 2/3rds, yellow is 1/3rd to 2/3rds and red is below 1/3rds.
Additionally a tooltip shows the exact health percentage.
______________________________________________________________________
Pros:
- Enables selfcast on double click
- Enables caster to cast on party members with small mousemovements
- Easily indicates who needs healing first or who requires a buff
- Works solid despite every patch so far
- It does not include RAID members (doesn't take over your screen!)
Cons:
- It does not report correctly with Healix, it only reports the caster casting on themself
- It shows on items that do not require a 'group' popup (armor kits, bombs, AoE spells etc)
- Clickable area seems a little small
- Not every class needs popgroup so it needs a quick disable button
- Does not include RAID members (just when you were a confident mousecaster!)
