If you highlight and make a new feature from a section of text in Productboard, that highlighting remains, so that you can hover over it and see that you made a feature from that part of the feedback text. In Savio, you can do the same, but the highlighting does not show on the feedback anymore, so you can forget that you made the feature request already...and do it again...and again :(

This may be similar to the request: "Link from feedback to feature request." I was not sure?
