Hi!
First, thanks so much for this incredible free software. I had an idea, I am not sure if it's already possible but I couldn't find this feature.
When you analyse a game (3-ply), you often find afterwards when you 4-ply the moves marked as errors, that either they weren't as bad as they were evaluated by the 3-ply or they weren't errors in the first place.
It would be great to tell the software to automatically 4-ply the errors, so when you review a game you don't waste time double checking manually every error.
My 2 cents,
Thanks!
