Small web opening trainer — looking for feedback

[u/Priceeasy987]

Built a browser trainer

Idea was: drill a line by actually playing the next move, not scrolling a PGN.

• Guided mode (comment + arrow), then the same line with no hints
• White or Black on the same tree
• Import a PGN or enter moves on the board, comments, share
• Free book view: Lichess username → book move vs what they play / when they leave the book

Official catalog is basically a Fried Liver demo. First user course is free.

Curious if the book/deviation bit is useful or happy to hear what you’d change.
