Yes, thanks, Maudland. I'd be interested to see your screenshots.
The decisive reason for reverting to the previous design for now is the errors that have been cropping up, on all puzzle types. Even though it's probably always possible to work around these errors, it's likely to annoy some players. And there's a possibility that new players may decide to abandon Chi because of occasional unpredictable happenings. I'm sure I can ferret out the causes of these problems and overcome them.
As regards the broader issue of whether the new system was an improvement, It seems inevitable that people's opinions will differ. That might depend on a player's style of play. Also, as a few comments have shown, the needs of someone playing on a phone are different from the needs of a player on a laptop or desktop computer.
Maybe the ideal resolution would be to give the player the option to choose the approach they prefer.
Thanks everyone for your input. Further comments are welcome. And thanks especially to Willember, who took the trouble to join the forum, to explain his experiences.
