@Adriano Faria I actually tried that same filter but I see you used the condensed view and that looks much cleaner. But this would be useful if it could be added as a permanent link for all users not just as a personal AS. Can that be done (even the condensed view setting)?
I think I understand what IPS wanted to do with the AS but it's still very rough around the edges. Trying to display all the activities (Board, Blogs, Gallery etc.) on one page is mission impossible. Having tabs or a similar solution would enable different views for different content types. Or maybe just group the activities by content type. And if the user wants to see all the new topics or all the new images added, expand that section.
