Added keyboard navigation to Pgn Editor. For selecting a move in a given position use the Up and Down arrow keys. If you switch to the "Book" view, you can see which move is selected, but keyboard navigation works in any other view as well. To make the selected move use Arrow Right, to go back one move, press Arrow Left. You can go back to the starting position with Ctrl + Arrow Left and to the end of the line with Ctrl + Arrow Right. Move ordering can be affected by setting the training weights next to the move. Moves are ordered according to the first weight ( my weight ) and if this is equal, than according to the second weight ( opponent weight ).
I'm not sure if lichess study allows this, but now you can merge multiple PGNs at once ( best if the PGNs are separated by two empty lines, but the parser is forgiving ). You can monitor which game is being processed in the "Merge moves" textbox. Yo can specify a ply limit up to which the PGNs should be merged in the "Max plies" combo. If there are a lot of PGNs, it is recommended that you use a low ply limit. Wait patiently, there is some delay between processing each game in order that the server and the client are not overloaded. Building a book from multiple PGNs is an expensive operation.
