We've improved the design of link cards on Dub to make them more readable – without sacrificing functionality.
The QR Code modal has been moved to the ⋮ dropdown on the right. It can also be accessed via the q keyboard shortcut.
The link creation timestamp has been converted to absolute timestamps (e.g. Mar 26) for links created more than 24 hours ago. This is similar to the way Twitter displays timestamps, and has better readability (as opposed to 110d ago).
