I do not think there is a way possible currently. So, this is also a feature request.
The number of favorites I have on SO are increasing and it is difficult to find a particular one that I am looking for when I need it, defeating the purpose of marking it as a favorite in the first place.
Marking questions as favorites on SO is a way of bookmarking that lacks many things. For example - I cannot categorize my favorites. It would be excellent if I could tag them or something (add a personal note as a reminder? though tagging is better) so that I can easily fetch the ones I need.
I know I can do this by bookmarking ALL the favorite questions in my browser and tagging them there, but that is just too much work. It can be done here on SO itself in a better way.
What do you people think? Do you agree? Do you disagree? How do you tackle this problem? Since I could not find a similar feature request here on meta, is there a way of dealing with this that I am not aware of?
