i have a stupid suggestion i know 99 pour cent it will be no but let s try is it possible to have a share or copy link button behind quote button it can be helpful if we want to share some interesting post as a references in different other platform like facebook twitter telegram .......etc
The share link button won't be necessary, at least not on this current forum software. Since sharing and copying a link are almost the same thing for social media platforms.
You can still just manually copy a link to the post of the topic you want to share on other social media platforms and then post it there.
