Very impressive update!

I'll need more time to read, study and understand... explore and try out.
Tried out ACIS fillet of a box.

Minor typo in Notes: "didsabled":
Update windows installer
Add checkbox to installer for "Create file associations", so that changing file associations can be didsabled by the user.

(Windows 11 "Defender" very briefly blocked install.)

I suppose ACIS company charges Triple Squid Software Design a fee per user?
