Very happy with the extension so far and look forward to seeing it develop further!
One issue I've noticed is that on a page which displays the member list we have a "random member" module which works fine however when a search is run on the member list the module displays the same results (ie if you search for "simon" it'll show Simon's profile in both the search results AND the random member module - so it's like the module is getting a filtered list of users from the search rather than just ignoring it and showing a genuine random user.
