Wow, that's a lot of work that has gone into properly identifying them. I just wish they were easier to tell apart, one semp can look like dozens of others depending on all kinds of things. On the other hand, instead of all the incredible colors, sizes, textures etc that are already available or being created, they could all look the same. I suppose an occasional bit of fixable confusion is preferable.
Kudos to all the good folks who have put so much time and effort into sorting it all out for the rest of us.
