Custom item tabs

[BitBork]

Hi there,

Great mod when looking for a more vanilla alternative to JEI/REI.

Would go a long way for pack devs to make it possible to edit recipe book tabs and what items are in them, what icon it has, what's grouped etc. Is this possible at all?
I tried using MoreCreativeTabs to do so, but BRB does not pick up on those changes. Maybe a compat with that mod could work? Alternatively using datapacks could make this possible?

Keep up the good work!
