The ability to drag and reorder columns in tables. Specifically, one customer needs it in the Meeting Activities page (they want the 'Booker' field to be further on the left because right now they have to scroll to see it).

Their workaround is to download a CSV, open in Excel, then sort and reorder. Ideally, we'd keep them in the app as much as possible, and this seems like a simple way to do so.
