When I open the status window, I get a continuous readout on the state of my char - hp, nano, running nanos, remaining duration on each nano. I'd like to see that degree of information on the pets on a continuous basis.
Perhaps add a tenth window hotkeyed to Ctrl-0. This window would be dynamic, containing a section for each current pet. The sections should always be sorted with attack pet on top, mez pet on bottom - I get annoyed sometimes with the /pet report command because I have to make sure I'm looking at the stats for the right pet.
For each pet, there would be a red health bar. There would be a blue nano bar for pets where nano is relevant. There would be an NCU section just like there is on the Ctrl-9 window. This would let us see what buffs/debuffs/roots are running on the pet and would let us see how much time is remaining on them, just as it does for nanos on the player.
It would be nice to have an AggDef slider for each pet as well, but I think that would conflict with trimmers.
