First, I love the addon and the way everything looks and works.

The only thing stopping me from using it as my main raid frame is the lack of raid buff|spell customization.
Such as a filter list per spell (hide|show), position options of icons, and the ability to show certain buffs (only if missing).

For example, I'd love to have the same options as "Enhanced Raid Frames" or "RaidFrameSettings".

Perhaps an easy solution could be to hook into the Blizzard Raid Frame UI so add-ons like those would overwrite Z-Perl (raid buff) behavior, or roll your own customizer.

This would be very handy for healers and those who only want to see certain spells or missing buffs.
Thanks for considering my request.
