I think it would be really useful to be able to create extra block sections (other than list, pen, etc.). There could be a button to create different sections, and to give them a specific colour. That would be really useful to order custom functions.
I suppose it would make it a bit difficult to look through the code if someone created a lot of them, but it would make it easy to sort out custom functions that didn't fit into any other section.
I don't think we need Supports in the forums yet, but you could add suggestions to the suggestions.
There's so little forum posts that i think saying support doesn't help much.
