It seems there is an option to play the tactical puzzles blindfolded, which is very interesting. However, after I get them right or wrong, I would like to analysis variations with the pieces visible, but I don't have (or I'm not seeing) the option to make the piece visible in the side menu. I have to switch it back in "Preferences" and lose the position I was playing. I think making that option available would be useful.
