Sometimes I see a very interesting question, and want to follow it. But as my favorite list grow bigger, it's hard to find/reference a question again. And I think a favorite question categorizer maybe good for orgnizing my knowledge, such as: here is the folder for basic Java, there is the folder for Grails. And I may take some note for every favorite questions (why I like it, which lessons I should remember?)
In short, is there any way for me to categorize/take note for my favorite questions? (such as tag, or user-created collection). If not, I think it will be a good feature.
