Bugged categories

Recently, I found out if you create a category with a lowercase primitive category name, it does this thing.

It also shows the primitive blocks in Motion, too.

Also, when I make a block, both categories get highlighted

and it defaults to the primitive category.

I couldn't find out how to add any blocks to the custom category.

Yeah, well, if you think identifiers are case sensitive you get what you deserve.

I think this is a pretty low priority bug. :~)
