Hi Andy, it has a lot more options than the default CTRL+L and if you need those, you will be better off, using the Addon…but then it makes sense to use CTRL+C all the time, instead of CTRL+L for some and CTRL+C for other situations…
The behavior for the Modifiers is at the moment the same, which ever method you use.
There is a difference in the Undo behavior, though, if you Undo a CTRL+C, it (also) undoes the action before the ‘Modcopy’.
