When you go to a person's profile you can either sort their programs by number of votes or by recent. This can make it difficult to find related programs if they have a different number of votes or were made at different points in time; especially if the person has a lot of programs.
So I have a suggestion that users be able to sort programs by what folders they are in. A user would be able to create folders and put related programs into one folder. Just being able to put programs into folders would be really helpful for keeping my profile organized and easy to navigate through. Also maybe you could make nested folders, although that's not really necessary on khan academy since khan academy users are unlikely to have more than a handful of programs that are related to each other.
I'm thinking that it would work similarly to Windows 10's File Explorer. Unlike adding backgrounds to a user's profile or making it possible to get to a person's KA profile from their support profile which are both fairly easy, I understand that making a folder system would be a lot of work and somewhat complex so I know it probably won't ever happen, but I do think it would be a great improvement to Khan Academy's Computing Platform.
