The main practical use for this for a real chessplayer, in my opinion, is to view games either online or in a chess book. You certainly need a "back" button for that. I see why "pub" mode was used to start, but I think that most people playing in pubs and thus in the same place at the same time should use a real chess set. Spectators are not going to be gathering around your tablet kibitzing, I predict.

There is every reason in the world to use electronic versions of chess for playing thru famous games because you can re-setup the pieces instantly, remember games, and analyze them.

The original charter of "Miniature" was to make it usable for online chess. I don't have it installed now because memory is precious and because there is not yet any use for it as far as I am concerned.
