"Buttons & Toolbars" vs "Script Buttons & Add-ins"

I am just wondering what's the difference between those two sections in Downloads area? I guess the primary idea was that the first section should be simpler, with modest scripting while the former would be more complex.

Correct me if I'm wrong, but it seems to me that lately this complexity borderline is fading more and more. It seems to me that those two sections might be united. Or am I getting something wrong?

Once things are organised we will probably have a single category for both, and tags to let people slice & dice it however they wish.

If you're just looking for a button that does something, you won't care if it's a script or simple commands. But if you're looking for examples of how to do something with scripts, you might. Tags finally allow us to do that, which wasn't possible with the old forum.
