For the code search one annoyance that they introduced was, that one needs to be logged in to search a project. Another annoyance is how the search works. Why, oh why, do soooo many programs/websites/software things have issues searching for a simple 100% substring match? There should always be an option in a search for most software, to search for exact substring without involving any magic. Then the checkbox to optionally ignore case. Only when this basic search functionality is ensured, should they care about developing anything else.
