This should be quite easy to implement. I think it would be great if could we have:
1. A User repository for macros in the Users folder, e.g. My DocumentsMy Alteryx Macros
This would make it easier to install macros without needing any administrator rights
2. A right click operation on a yxmc file (or a menu operation in Alteryx) that Install the macro ie. will move any macro into the folder above.
This would make it very simple to show new users how to install any macro you send them
Both these ideas will make it easier for partners and the Alteryx user community to share macros.
