OK, I did not test long enough :-)
... Of course we have to allow ourselves to make a lot of chess move mistakes to learn a lot. I have now added a scroll bar also to the new Tutor tab that lists our mistakes. Remember that mistakes are not failures, they are learnings :-)
Anyway, in a flow of creativity, I also added a new tab named "Analysis". It looks like the Engine tab, but it presents the server engine thinking. That means that it does not consume any extra CPU and you can compare if you like the Engine tab thinking which is a web client Stockfish implementation against the server thinking. The server thinking is at the moment not updating so fast, but its a start.
I hope the video making will be succesful now Antonio !
