It has been a while since I posted, but I have been making some good progress on UIAssist v1.8. The main new feature is a what I call an Active Clothing Editor.
Essentially it rapidly shows what clothing items are currently active on a person and allows you to switch them on or off (i.e. "Remove") and to toggle the Sim Undress state. When reversing Sim Undress it also Resets the sim - so clothing goes back to its default state.
Hope to have v1.8 out soon. Likely to be the only release this month due to summer holidays!
