Context: The plugins which ship with Studio are now are pre-compiled to bytecode and don’t include the source code at all in order to speed up Studio load time, so there’s a good reason they can’t be edited in Studio.
I’m looking into what we can do about this. Given the ever increasing amount of studio functionality delivered as plugins it was unsustainable to include the entire source only for it to never be used outside of a very small number of users forking it. But as you point out there’s benefits to having them available in some other way.
In the meantime, here’s the most recent Dragger/DraggerFramework code if you need it: DraggerFramework.zip (395.5 KB)
