Allow users to search for Epics/Issues (or at least view a list) when adding them to the widget
Problem to solve
When users want to add an Epic or Issue to an issue they must first copy the link for the Issue or Epic they want to add. Worst case scenario, a user clicks [add], notices they need a link, navigates away from the issue, searches around for the Epic or Issue they need, have to then find the issue tab they were on or search for it/click back multiple times, then finally can paste the link. This doesn't seem like an ideal experience. How might we allow a user to search for the Epics and Issues they care about within the context of adding and in the issue itself?
What does success look like, and how can we measure that?
Users workflow is optimized and not interrupted by having to navigate out of the page after clicking [add]. I would assume users would expect to be able to choose a preexisting Issue or Epic after clicking to add but this is something that could be tested. The desired outcome is that users are able to quickly create issues in a way they would expect without having to perform multiple copy & paste actions.
