So I have this peice of code I've been working on for quite some time. It's a ListView with a search filter. Inside each row, it contains a user Image, a User's name and how many friends they have in common. Also the row contains a button each, for actions.

I'm just indeed of some code refactoring, maybe some guidance? Different collections that I could use to tone the heavy code down.

Thanks, Peter.
