Code cleanup
Removed the handle thing as requested. Sorry I didn't do a proper clean up last time. BTW, I won't submit anymore addons to the extension platform. I'm doing all of them to try to make Blender more efficient and be a better tool for managing big files, big projects, like the render manager, collection manager, light editor (lights, light links, light groups), all areas where Blender fails to provide adequate UI or tools. Blender is clearly designed to deal with one object at a time and the Blender Studio never worked on a big project. They only work on short films. But any studio working on huge projects (like we do) need them. Maybe in 10 years AI will be good enough to write clean code but it's clearly not the case right now, so I will stop submitting. I won't even bother with the major addons I submitted before. A few people volunteered to help but they all let me down. So... I quit. I don't take your comments about getting tired of reviewing my stuff personally, or as a personal attack. I fully understand your point of view. It's just that there's nothing else i can do at this point. Cheers!
code fix
Initial release.
