This is a great add-on! The only improvement I can think of would be the ability to add multiple script folder paths and a drop-down menu in the panel to switch between them. This would be useful if you work with multiple Git repositories that use different scripts.

Good add-on, but there is currently an error during FBX export if an object has custom properties (these must be deleted beforehand).

Lifesaver! This makes it possible to easily apply Shape Keys to the Basis:

1. Do a custom mix and make sure that all other shape keys that should not apply to the Basis are set to 0.
2. open the ‘Shape Key Specials’ menu (drop-down arrow next to the ‘Shape Keys’ list) and select ‘New Shape from Mix’.
3. set the value of the newly created Mix Shape Key to 1, open the ‘Shape Key Specials’ menu and select ‘Swap Vertecies at Shape Key Value’
4. Delete the old shape keys that contributed
5. Set the newly created Mix Shape Key back to 0 and delete it.

Done!
