The "play" button has been on the right in the puzzle menu for a long time.
In the latest devprev, the "quit" button has moved into this position, at least when you start the client.
This means experienced players will end up closing the client instead of opening the desired puzzle.
I suppose in time that we'll get used to it, but I would have prioritized fixes and other changes over this one.
As long as we're re-arranging things, I would have moved the "play" button all the way to the left in its row on the puzzle menu. Maybe move "main" menu toward the left edge, separated from the other buttons.
After you open a puzzle, you'll find the "quit" button has been removed from both the puzzle menu and the main menu, replaced with "cancel". "Quit" closed the client, while "cancel" dismisses the menu, returning to the current puzzle. This change makes sense to me, but again it seems to be addressing a problem we didn't actually have.
