I would like to see a bit more customization in some of the options brought up during a token's selection.
Some games like Savage Worlds, classic Deadlands, World of Darkness, etc have conditions, wounds, etc that use a sliding scale that can't really fit into a number. It's easy to track hit points, sure, but when health is represented by different body parts or a row of boxes that have three different levels of damage it gets a little more complicated.
On a cosmetic note, being able to pick how many fields are above the token, what symbols show up next to those fields, or what colors those symbols are -- it'd all be pretty handy. I know this is probably fine detail stuff in the face of a beta with bigger things to worry about, but I felt like I should at least put it out there.
