MamaELM THANK YOU SO MUCH FOR THE SUGGESTIONS aaa I'm so sorry I'm kind of out of commission this week but I see a lot of stuff I'd love to add in as soon as I'm free!! In particular, species and literature features are both something I really wanted to add in development but never got around to, thank you for reminding me!!
That behaviour with art thumbnails is quite odd and I'll look into debugging it when I can, thank you for letting me know and sorry about the trouble!
