Lack of interest Recent activity tabs that can be filtered into forum groups

So what I was thinking was that if I ran a football forum for example, instead of having to click into each individual Football section, there could be a way to group posts (within football related forums) so they all appeared together. For example you could have individual sections for Premier League, Championship, Transfers, Matchday and by having some tabbed options it would display the latest threads from ALL of the sections.

You could also do the same with "Music, video and films", "general and support"

You may have a general section, support section, etc etc, - These are all then grouped together into a tab to display ALL the recent activity.
