Only Snap!Shot and minor events should be under it, while the major ones, which Snap!Conferences are, should each have its own category.
SnapCon202 was the 1st thing so it got made its own category
But then SnapShots and SnapCon2021 came along and events was created
So SnapCon2020 is actually the outlier
Or make a category called Snap!Con and all the 2020, 2021, 2022 Snap!Cons subs.
I vaguely recall that Michael wanted to move Snap!Con2020 under Events but discovered that you can't recursively move sub-sub-categories or some such problem.
