The category feature that came with 2024.4 is without a doubt the best thing since I started with HA.
One thing that would be nice is to make the groups collapsible for easier access to the areas/categories/states that you currently are working with.
In the same line of thought, it could be usefull to be able to hide some categories from a table.
For exemple, I use keymaster from HACS. It creates a bunch of automations that I can’t edit. I use a category zzz_keymaster to put all these automations at the bottom of the table.
If I could, I would give this multiple votes
