Would it be possible that if a user views revision history and timeline, if edit summaries contains a link, then this could be opened by clicking on it, rather than having to copy and paste the link?
I can imagine some situations where the edit might be accompanied by some link, most often link to the relevant (per-site)-meta discussion. (E.g., if I change the tags, I might briefly explain in the edit summary why the tags had to be changed and link to post on meta where it is explained in detail. The same goes for other types of edits.)
According to this post the links are clickable in the iOS app. Having the same on the website (be it desktop or mobile version) would probably make things more comfortable to the users, too.
