I'm a big fan of the favorites feature. I usually mark questions with good answers of code snippets for later use.
Most of the time I can't find the favorite I'm looking for so quickly as desired. I know I marked the question in Stack Overflow, but it takes time to find it again, because of the following reasons:
- lot of favorites
- lot of answers for a question (last time I was looking for an answer in the question Hidden Features of C#)
- the question title is not always what I'm looking for
To make favorites more useful I suggest the following features to be added:
- Allow to mark an answer as favorite
- Allow to tag questions with own tags (those tags are personal and can not be seen by others)
- Search function over favorites
- Allow to add a personal note to a question
