FAQ

Q: Why not split the table?
A: I think the table isn't big enough for a split to be valuable, and it's easier to check for all the features you'd want with one glance, instead of going back and forth between two tables.

Q: xECS isn't here, why's that?
A: Idk, ask about it in a new issue, it might be too niche, or something.
