I recently did a ton of overhauling on Card Hands List. A lot of it was behind the scenes, but some of it improves the UI/UX, especially with horizontal scrolling through the Cards in a Hand.
Adds verified support for Foundry VTT v12.
Adds retention of horizontal scroll positions when interacting with Cards and Hands.
Consolidates Unset and Set Defaults context menu options into one. You can now choose "None" in the dialog to unset the defaults for a Hand.
Massive code cleanup and improvements. If you happen to find any bugs, please file an issue.
