1. Add an icon to the FuBar (as an option, preferably something other than the anvil used for DurabilityFu and DuraTek - a Shield would work well). When you have alot of numerical display on your FuBar, it's nice to have a small icon to help differentiate them.
2. An option to display crushability percentage on the FuBar would be great. Simply show the percentage chance of a crushing blow being landed on you. For me, that's the only value that matters for realtime feedback (the others can stay in the tooltip).
3. The FuBar data (Avoidance) wasn't adjusting for me when I used Holy Shield. Seems like a bug.
Keep up the good work.
Oh, one other suggestion:
4. It'd be great it AbramsFu was "intelligent" and disabled itself for classes that it doesn't really apply to (ie: it's only enabled when logged into a Druid, Pally, or Warrior), or at least to have an option for such. It seems like Tankadin does this, as do several other class specific mods I use (Cryolysis).
