Marko I don't know if my reflection is right and valid but I think it is preferable, to avoid confusion when someone is looking for a function, that the names of the functions should be changed and highlighted what has been changed and why.
example:
;; original LM:Arc->Bulge Arc to Bulge - Lee Mac - mod by M.R. > MR:Arc->Bulge
;; original LM:Bulge->Arc Bulge to Arc - Lee Mac - mod by M.R. > MR:Bulge->Arc
Thanks
