I also managed to fix the Units To Remove list, to show units like leaders and fleets. Not sure why units were coded differently than the other two lists, but easy enough to fix once I got into it.
I say "easy enough", now, but it's taken a lot of time to learn how to deal with these forms, these popup windows with check boxes and such. So now I can edit things like making the Conditions box a bit wider to accommodate the condition numbers, and making the Units To Remove box narrower. Big trick was figuring out where(?) the damn conditions were defined. It's not in the code, but in the .tpj file. So I learned something new there, and can use that info for something else I want to fix. Onward!
