Disappointing

The UI is atrocious. Theres an undo button floating randomly that means "go back" but theres no go forward.

The "position of the day" is always that starting position. I have no idea what the point of this is yet it takes up 1/4 of the main screen.

The quizzes ask things like "whats the 2nd most popular move here?". Who cares?! Sometimes it asks the same question twice in a row. I expected to be given an opening, say, French Defense, and then playing as white or black try to stay in book.

The catalog of openings is impressive, but they should be further stratified as currently the list is so long that its difficult to navigate. E.g. The top level of the hierarchy would be Kings Pawn, Queens Pawn, etc.

Id like to be able to move pieces around the board and have the app tell me the name and variation of the opening, if any, but theres nothing like that.
