Hmm, I dont know what you mean about stickies, but here is a mock up I made

The X and tick are representing filterable threadfields
Using the filter box
The idea is, if you click forum, thats easy, it takes you to that forum, but if you click on the X or the TICK then the forum display of this forum display (the one in the mockup) will filter showing all threads from those three forums that have the filter.
From the thread thumb you can go straight to the thread using the thread TID.
And yes, it does look remarkably like my set up
