Things I am going to add after trying the tool out during my game session.
Add "note" field or "Tag" field to each creature. I have multiple sets of d6 dice and I use them as "tokens" on the battle map when we have large battles. I will set out the dice face up with a specific number (1-6) so the player can say "I am attack blue 6" and w/o getting up I know which one they are talking about. It would have been nice to add a "tag" or "note" to the creature in the encounter list that would associate it with the dice so I could just add "green 3" or "blue 2".
Add "full status block" quick list option so if there is something not listed in the short status block you can just click for a menu popup that can easily be dismissed.
Add a "simple attack" attack to every creature. Some creatures use "by weapon" and that might change so having a just an attack roll for them would be nice.
Add right click (or some other menu option) to add a modifier to a attack or damage that persists once set.
Add full attack matrix use, currently it's set to just use THACO from the matrix. Pretty accurate for the most part but I got the data in might as well use it.
Clean up right click to re-attack and re-damage. Right now it's double rolling both on right click (know why).
Work on better status block listing, need HD I think.
It was great not having to pour over my monster books during the session.
