seems like I’ve +1ed this in both 2020 and 2021 LOL - anyways this is definitely necessary, probably the site feature I’m most passionate about adding!!! all the arguments against adding characters to multiple folders fall flat, folder descriptions and tabs are not adequate alternatives at all!! for one it’s ridiculous that we even have to make a completely identical clone to our character as a tab solely so they can fit in multiple folders. and I should not have to say “hey, this character that’s really vital to this story can’t be in this folder because they are already in another story” in the folder description, especially when it would completely ruin the look and feel of the description. it messes up the entire layout, people probably won’t even see the link and it’s just more logical to be able to put the character in the folder LOL. it’s a slightly better alternative than tabs, but it is not a suitable fix to the issue, FAR from it.
tags can be helpful in some situations, alongside making worlds, but there are many things either of those cannot fix like characters being from multiple different stories.
