We can see how that could be appealing to members. However, this website is first and foremost a discussion board, not a dictionary/encyclopedia. The community already has excellent reference resources such as BS01.
Actually, the list is already arranged by most recently active.
Your browser already has the built-in functionality to do that. Scroll to the bottom of your topics list (in order to load all of the titles) and then select your browser's "search/find" functionality (CTRL-F on most desktops). That search bar will search through all the HTML text loaded on the page. Make sense?
Since there are relatively few active community projects at the moment, we've decided that a whole new category isn't warranted right now. However, if there's a rapid influx of new popular community projects in the future, we may reconsider.
