It'd be nice if the Public Profile page included a link to that person's Interfaces list.
There's currently a Yes/No value under Aditional Info/Interface Author. Maybe the "Yes" value could be replaced with "View Interfaces" linked like is done on the download page Interface Info table.
Reminder: we talked about a mainid filter for downloads/index.php
Related: Once that's mainid filtering is working, it'd be nice to have a link to Patches & Addons (filtered with mainid) on each download page's embeded table. I'm thinking next to the [upload Patch][Upload Add-on] links.
