I really like the tick marks in some answers to this question.
This would particularly useful on Software Recommendations, where users ask us to recommend software with a list of features. In reply, we could list the requested features and whether the recommended software has them, letting the OP (and future readers of the question) decide how much he really wants/needs all of those features, or if some of them were perhaps just "nice to have".
Runs on both Linux and Android
Costs $2.99 (but is free for non-commercial use)
However, they are being created by Imgur images.
Is it possible to expand our Markdown to add a green circle with a tick and a red circle with a cross (maybe a few others, like question mark)?
I originally asked this on Software Recommendations Meta, and someone there suggested "GitHub flavored Markdown", with which I am not familiar.
