I'd love to be able to slap some quick filters on my homepage on Stack Exchange.
Simplest form: Next to each site at the top right, put a little eyeball that I can close and open, with a "close/open all" eyeball at the very top. Then, if I just want to quickly see new/hot/whatever questions from the Trilogy, I can quickly close all and then open the Trilogy eyeballs, four clicks to seeing an aggregate of the Trilogy questions.
More Complex: Allow me to save "views". So, say I wanted to create a view of three loosely-related Stack Exchange sites. I'd:
- Close all eyeballs
- Open eyeballs for "Cooking", "Bicycles" and "Home Improvement"
- Name that view "Domestic" (or something)
The view would appear as a link down below the site list. When I clicked the link it would toggle all the eyeballs to create the correct view.
