If yours allows to work in units other than feet/inches and has better code, I could as well delete my gist to avoid confusion and spreading of bad code. Will try to check soon.
I made it so you can show 2 dimension at once and adjsut the decimals and to show total or sepatate shape areas

Hi @nanoSpawn i have 2 versions i was working on. I noticed they still have issues and wonder if it can actually be solved. Checking if items are compound shapes with cutouts is very tricky!
ive havent touched these in couple months, i added both versions i was working. I remember there was something odd going on in them. There could be some alerts in there as i was doing some testing
You can find them here

PS this version is not based on your code, but its from the other fork from Bryan Buchanan and @alijaya contributor
I added a different UI and made it save items
