Credit for most implementation goes to KT Command Node and KTUI. I merely pulled out the parts I wanted so I didn't have to jump through a bunch of hoops to get the UI on whatever models I wanted.
Models start with their wound count at 0, you can set this via a right click menu option. Click the wound counter to pull up '+/-' buttons to modify remaining wounds.
Right click the order token to swap orders. Left click to toggle Ready.
Hover over a model and type a number to spawn a range circle (measured from the edge) of that same amount in inches (so type "2" to see engagement range). The circle should be colored to your player.
Right click and use the Save/Load Position options to play around with movement without needing to Ctrl-Z and reset the whole board state. Save Position also forces the model to encode its state into JSON, so it might help resolve any weird issues on fresh models.
