Well that got resized a bit I can post a bigger version if needed!
Things to note!
Maintained window Don't show until canceled buffs please move those to somewhere else I don't care.
Raid window, please only show the three groups you AREN'T in then make it so you can drag and drop to the group window. This would free up a TON of space and still allow them to be moved separately.
Hotkeys recast show or at least the option for it in hotbar settings, make out of range and out of power more visible( being colorblind Its to opaque for me to make out
) Show timers for items & item macros.
Player/Group Why separate these? The red bar underneath is the pet health.
Target window show hp and power percents.
Compass ad a fancy orb or something where the arrow thing is and make that the start button.
