I recently installed picmi on my Pinephone and I quite liked it a lot. It was just unsolvable due to the lack of right clicks. To improve the situation I propose one or both of two changes: 1. Simulate a rightclick on long press. 2. Mark the board as solved when all fields that have to be left clicked have been left clicked.
Hi, thanks for the report! To set expectations, Picmi isn't in active development. Your suggestion 1 sounds useful and easy to add. Maybe you would like to contribute a patch? Another possibility is a toggle to switch between marking X's and boxes. Suggestion 2: There were complications around this due to non-unique solutions if I recall correctly. I don't remember the details. That's why one currently has to mark all X's until a solution is accepted.
