Yeah, it's not all too stable.

Timeseal, changing the highlight color of a piece being moved, the chess engines and a few others causes a lock down from the application.

There's a trick around most of them but it takes several hours to understand it's behavior.

I'd love to make suggestions but, as it is, I can watch live international matches on a 480x480 board with an analysis engine to show the best move.

It's easily good enough for me.

Any requests beyond that would seem petty for sure.

So yeah, it's not perfect, but enjoy what is there because with all of the options available, it more than makes up for severral of it's shortcomings.
