Suggestions for xperl, sorry if they are already stated somewhere else.
1. Add the shield or some type of icon so we can tell whether or not the spell is interuptable.
2. Make it so we can see what our target is casting as well as target's target.
3. Make it so buffs can be above and debuffs below the player/target frame and/or vice versa.
4. Fix focus frame issues with X-perl.
5. Enable so we can use the new Marking raid icons while using xperl.
This has been my favorite mod for the past 4-5 years. Keep up the good work! :)
