Working from the sprint wall works better from lightning (especially the right panel filters and charts), but I can't figure out how to update custom fields on a work object. I'd be fine with being able to open the full work record in a separate tab, or better yet being able to add custom fields to the work record pop-up. I hope I'm just missing something - any suggestions?

(We exclusively use user stories, if that makes a difference.)

Thanks in advance!
