Bonjour Eric
I can understand that - there are 2800+ sides!
The test that if no side cuts another is really useful because if that is the case, then you don't get a CoA – which tells me that somewhere I have something wrong – usually a double line from a trim that has joined into the polygon – so when it goes to be CNC cut, there is going to be an error. So I can search for this and correct it. Only when I get a CoA do I know that I have a simple polygon and good for CNC. It has made checking for CNC much easier for me, which was an unexpected side-benefit
My strong personal preference would be to retain the test and enable the calculation when you want it.
Can you do it with Action >> Length and area? That would seem the logical place. So you select a polygon and click Action >> Length and area and the CoA appears. Actually no real need to display the L, P & S data because that is already displayed in the Edit pallet. If so, maybe change the name to Area or Centre of Area.
If that's not possible, then a simple checkbox in Preferences would be just fine as far as I am concerned.
After all it's a very specific bit of data – not something you necessarily need to see all the time.

PS: I can't tell you how useful CoA's is for me – it does sail areas, centre of lateral area of underwater hull, all sorts of things that I hadn't even thought about originally. Made a huge difference to the speed I can do calculations.
