My suggestion is an option for compact cards in Work mode.

I recently worked at a place in a team of 6 people where we had our stand-ups by a 60-inch 1080p screen. A lot, if not most, of the time was spent scrolling back and forth to find the issue we were talking about. (The sudden appearance of the details view also seems to consistently confuse people.) The place I'm at now has the same issue and has even chosen not to use Jira Agile for stand-ups for this very reason, which I think is tragic.

Cards as they are now in the (non-classic) Work view have a lot of empty space in all our scrum boards. The sizes of cards in Plan mode however is very compact, and contains enough information for the team to know what it concerns.

I believe people are still using post-its everywhere because a sprint will not fit in a readable manner in one screen.
