Lack hands?
The only one I’ve seen get off the ground is mine, and it’s practically done, there’s very little work left to do, besides updating when you post a new sheet.
We just need William to get over which set he thinks is pretty.
This is about the closest you’ll get, there’s new icons and icons moved so just switching to the old set outright isn’t an option. If you can get through the tutorials on compiling blender and updating the icons you can test it out.
