This question already has an answer here:
In short, can we have (or somebody tell me of an existing way) the ability to flag posts for personal review?
The reason for this is because I often see posts (mainly answers) that I feel need to be removed, but because I mainly check out the new questions I often avoid flagging a lot of them because I want to give the user a chance to improve the post. It would be nice if I could flag them for personal use, and then I could check my list for posts that are a few days old see if they still justify flagging to be removed.
Maybe "flagging" is the wrong term, I wouldn't want to have a feature that is specific for such a small number of users (or even just me). Perhaps something more generic like "memorable posts" or whatever. I don't really care what it's called, only that it would fit my needs.
EDIT: What I mean by "existing way" is an actual proper way to do it. Not a hack-around. If I wanted that I would create a Google doc and fill it with links. I think based on current replies that it is safe to say there is no decent feature for this so far
