Need help with grid2 - adding threat to grid; man%

Hello -I'm a big fan of grid2 and have it heavily customized. I'm struggling with two indicators:1) Adding some indicator of threat to the healing grid. Ideally, I'd like to see a tile border flash and turn red when a DPS/non-tank hits 80% threat, but I can't find any way to add a threat indicator reliably to the grid.2) When adding %mana text via a custom indicator, the indicator doesn't show up on all mana classes. It's always on my own tile, but seems to only show up randomly on other players tiles.Does anyone have any suggestions? Thanks!
