I see the most important issues as: better, readily-available visual representations of the trash, mats, Durations, and Journey tokens. Fixing the ability to name cards so that Wishing Well, Mystic, etc. work correctly. Being able to see what all of the cards do in a split pile (Knights/Castles included). Not needing to click on the log, and needing to look at the log less in general.
The out-of-game client needs better guidelines for users, particularly what familiar cards are, and how they operate. A simple link in the client to
Chris's unofficial FAQ would be a great start.
For someone who has played with all of the cards already, and has played hundreds of games, these things aren’t as severe. But right now I avoid recommending online Dominion to people who are new to Dominion, because I don’t think it’s friendly enough to beginners.
With the exception of ratings, which are important so that beginners don’t get routinely crushed, and a better interface for finding matches, none of the things on ShuffleIT’s
2017 priority list seem like they should be even close in priority (even you, Stash!).
