In Jira Server, I could get Epics to show up on the left side when in backlog view (see image). I'm now working at a new place using Jira Cloud and I can't for the life of me figure out how to get that to show. It was VERY useful to have it there (rather than create an issue filter, which I know I can do but it's not that helpful). I've scoured the internet and the community here and can't find it. Anyone?
