If I open a question that I have already answered, it would be nice if there was an icon or link telling me something along the lines of "You have posted an answer to this question." This would scroll me directly to my answer and let me reuse that information.
For example, this could look like:
A while ago I worked on some thing and posted an answer, but after a long time I am now searching for it again and checking the answers but unfortunately I cannot find it. It would be nice if there was an indication that I posted an answer at the top of the page!
Note: I know I can view answers I've posted in my user profile, but it can still be difficult to find the answers I'm looking for, as I might have posted a lot of answers!
