I have re added gadgets to Vcarve (Gadgets Library | V12 | Vectric Gadgets). I recommend you view the tutorials before trying them out. I have not tried any out but please post here any that you do try and your result.
Thank you.
Bear in mind they are shared by all users. I could not find an install location that was private. For example, you should see a Gadgets / RnD / Test1 where I was playing with the API.
