I just had an interesting feature request from a user. It seems like it would be fairly difficult to do without access to the full database, but what she wants is to be able to limit a search to just the people she's following. For example, if she saw a link go by from someone and didn't remember who it was from, she'd like to be able to search for it.
I can think of fairly easy ways to code it using the API, but I'm wondering if something like that could be built into the web app.
