This might not be as much of a low-hanging fruit but yes, there have been so many other popular low-hanging fruit suggestions in this board that never got implemented -cries- which makes me think medium-hanging fruit like this won't ever be gotten to
I've seen maybe 1 new not-needed feature (the dressup scenes, which are awesome but........... and yes I'll argue that ChickenPaint was needed due to the phasing out of Java for security reasons) and 2-3 small not-necessary improvements (the changing of the text color against the background of the Space theme was necessary) over many years

if my numbers are off then they aren't off by a significant amount
I agree with RandomSia that the explanation shouldn't be in our rules, and I don't think we should even include an explanation space because I think that'll lead to the expectation that people will read the explanations -> more frustration when people inevitably don't lol
If we have multiple and customizable wishlists, then the name of each wishlist really should be self-explanatory enough; if it isn't or if it's a wishlist with a very specific purpose, then you can specify it in your trade rules, but I don't think we should have an explanation space by default.
I could see potential miscommunication between members who use the star colors differently; for example, there will be people who
* follow the rarity colors, going from purple = most wanted to red = very wanted to blue = least wanted
* follow rainbow order in one direction, going from red = most wanted to purple = least wanted
* follow rainbow order in the other direction, going from purple = most wanted to blue = very wanted to red = least wanted
* don't follow an obvious order like that, maybe assigning based on personal preference or something
But I don't really have any better ideas xD Just something to keep in mind.
I mean, we could have numbered stars instead, but would people take a low number be the least valuable or the most valuable? We already have this number confusion with the Rares List; I'm clearly not the only one who thought that the Advent List tiers were numbered like you would number lists ("you are my number one" "the first item on my Christmas wishlist is..." "name your top three choices") instead of like you would number the floors of a building where the very important people were at the top floors or like a rating system
People might also have wishlists of equal priority, but stars with different colors or numbers would probably imply that the wishlists are of different priorities.
I really don't have any better ideas other than to remove the color-coding and numbering entirely lol and at this point I think I'd take any implementation
@shelberina711 Glad to see you take over :3
