What piece notation in the settings "boards and pieces"?

What does this setting do?

Also "Move Classification Style"

I googled it, but couldn't find what their function is.

Also what does "Auto-watch top game", "Engine evalution" in "Live chess" section mean?

Piece notation is going to be for the move list:

• standard algebraic (Text) giving the piece abbreviation and destination 
• figurine notation which replaces the text with a graphical representation on the pieces 

This changes the visual representation of move classifications on the Analysis board (and probably embedded diagrams)

• Default is a graphical glyph before the move
• Traditional is text only, after the movr

Game Review is always the Default option

• Auto-watch roll automatically lol and the top game when you open live
• Engine evaluation will turn the engine on when watching games
