So basically, add a Pending Friend item on the Profiles tab, or show Pending Friends in the friends list, for example.
There's no official place to go see your pending friends. This could be a problem in the following case: If I follow a friend notification on the wrong profile, I can't friend them without changing profiles. I might put this off for some reason. But since I followed the notification link, it is now removed from my notifications. If I forget who sent the friend notification I'll never be able to figure out who sent it without just looking at every profile on Lit. Having this pending friend show up somewhere would be helpful in this case.
