In many cases the pre-comment of one move is displayed at the same
position in the move text as the post-comment of the previous move.
When this is the case, don't make a distinction between pre and post
comments in the "Edit Comments" dialog.
The PGN standard does not allow the '}' character inside a comment,
because it is used to end the comment.
Therefore this character is now replaced with '｝' (fullwidth right
curly bracket) when editing comments. This does not look great but is
better than making the PGN data invalid.
This is needed to avoid problems when dragging one of the R/G/B
sliders. With the default Android conversion code, the other R/G/B
sliders sometimes move during dragging.
The following settings can now be changed using the OI file manager:
* Opening Book Settings -> Book Filename
* Endgame Tablebases -> GTB Directory
* Endgame Tablebases -> Syzygy Directory
For string UCI options containing "file" or "path" in their names, add
a button that opens a file browser to set the value of the option.
The browse button is only available if "OI file manager" or a
compatible app is installed. The button is not available for network
engines because there is no way to browse the remote filesystem where
the network engine runs.
The new action "load deleted game" loads a recently deleted game from
the autosave file, without affecting the "last used file" and "current
position in last used file" properties.
The 20 most recently auto-saved games are kept in the file
DroidFish/pgn/.autosave.pgn.
Overwriting an existing game when saving a new game also auto-saves
the old game.
The analysis information is copied as text to the clipboard. The full
text is copied, so the "truncate variations" and "hide statistics"
settings have no effect on the text put in the clipboard.
Add new setting (default true) to allow input of moves by dragging a
piece from its source square to the target square.
This setting partially overlaps with scroll gestures on the chess
board, so when this setting is enabled, scroll gestures will only
happen if the starting square is empty or contains a piece of the
color not to make the next move.
