Soz if i'm being blind and this is already a thing, but a notes tab or something in teambuilder would be pretty neat ;o gotta hate loading up them older teams and have no idea why mons have those evs :<
Sounds pretty creative for me. And I think it would be very versatile if you have a set of notes for each pokemon individually rather than a set of notes for a whole team. Since some pokemon can run multiple EV spreads with different purposes, and putting those notes together about all pokemon's EV spreads can get messy, or can create a very large notepad. Idk, my opinion.
