INSET / EXTRUDE Modifier
I know that there is Face Extrude but I really would like to see a modifier that can be added to the stack that allows me to change the inset value without having to use an undo if I don't like the result. But the same applies to the extrude, it would be good to see an INSET/EXTRUDE modifier on it's own. I am surprised there isn't one around. I just dislike the Face Extrude modifier, it feels limited to me and it doesn't work in any other scale besides the default (ie CM, MM, FEET etc).
Can only hope someone will be kind enough to create one to share with us all.
