The "Select All" and "Select None" options, in the list of expansions for new tables, were removed when the new UI was introduced in February, and I really missed them. Setting up a game with a few specifically picked expansions required a lot more clicks than before. I was wishing that you would add something like that back.
I noticed the "All" button that was added in the last few days. Thank you so much. This change fixed what I thought was one of the biggest annoyances with the new UI.
