I am not sure if this was suggested before or not, but I couldn't find it by searching, so here it goes:
It would be nice that we could check a list of the recent 'seen' players on the last/past world(s) we've been in, in case of disconnection or we forgot to add someone we liked to speak to, this works well for games on steam that support it so VRChat should have it too, when servers have problems or I forgot to add someone, I would like to be able to go back to the list, scroll through it and be able to add who I missed or wanted to before. (if this shows multiple past worlds, it could say the hour:min and the world they were in or something of le sort)
[ps. the UI/GUI how it is, the tabs and how it shows players/worlds seems to be a bit of a cluster and disorganized, so maybe this feature should only be considered in the future when everything is redone/polished?]
