New feature, maybe not worth the trouble

I'm not sure if this feature was implemented in any other JEI/NEI alternative, but it could be nice to have folders on the item list (like Bedrock's creative list) these folders would need to be added by the mod devs or maybe by an addon. These lists would be minimized at first, but then expanded when clicked.

For example, AE2 could have a list for every facade that when clicked, it would show all facades. They would probably need to be highlighted when opened to clarify that it is a folder (they would be different from items, maybe by a + symbol like on bedrock).

This would help solve pages filling with stuff that you may need, but could be grouped in a smaller thing.

Though I'm not really sure how it should be when searching for items, showing the folder is good, but it wouldn't be the best.

Maybe I'm thinking about a problem that can be solved another way (Energy hatches in GT are hard to search.)
