I dont use datapacks but if Im searching for something specific I use them
If I just want to see new datapacks I dont usually use filters

When I am browsing just to see what's new, I don't use filters, but when Im looking for a particular experience then of course yeah, I do use the filters. I find myself using "Extensive" more often than others because those are the kinds of packs that I like; I'm not too into things that only add one or two unique items that appear only in loot, for instance, or individual boss mobs that don't have an experience surrounding them.

I don't know that there are any categories I feel are missing, but I might change my mind on this if some examples are given.

Well yes and no, if I'm on almost daily looking for some, then no, as I'm just looking by most recent. However if I'm trying to find something specific or have a particular type/vibe, then I use the filters. I find them very helpful.

i dont personally, every once and i while i scroll through the first 1-4 pages of the updated ones
