As one can see in this "thread ":http://developer.qt.nokia.com/forums/viewthread/7785/ Tags have a more prominent place for access now.
Starting to type changes immediately the list of possible tags. This is really great and helps a lot.
From my point of view it would be helpful to extend the functionality. At the moment one needs to decide for one tag to use in the search. A possibility to enter a second tag allowing a combined search for threads having the two tags in common (e.g. "linux" and "cross-compile") would be really great. Certainly one may wish to have an "unlimited" count of different tags, but in general a max of three I would consider as most sufficient.
BTW I have checked the "Advanced search", but it did not provide what I was looking for. Or at least I did not find.
