I think I've seen someone put footnotes in both questions and answers? Is this a feature I just can't find, a feature for only moderators or not a feature at all? Would it be an idea to have this feature if it's not already one?
The feature is available to all users.
You create a footnote by typing the following characters:
It will look like this: 1. Then you can change the number in the note as you like.
Would it be an idea to have this feature if it's not already one?
Beware that there are 20,000 feature requests on meta.stackexchange.com.
It's not that they never implement new features, but generally I hope to learn to make do with whatever the existing features are.
