First of all, I am very grateful for the amazing program.

It has helped me a lot.

However, I hope that can see the comments of the sgf when review the game, and I also hope to save the variation and Winrate.

I guess the author must be very busy, I can't wait and to try to make some minor changes.

1. Add the display the comment of the sgf (C tag): Forgive me very lazy, directly displayed under the variation panel, please ignore the ugly style :(
2. Add the ability to read and write the sgf with variation
3. By the way, write the Winrate in the comment of sgf for each step (C tag): Just a little try

Attached the codes and files, the code base on the release 0.5, and use the class (WrapString) of the Jim Menard. Thanks Jim Menard.
There are not many changes, not list the differences.

Just a reference for those in need.

Sorry for use the Issue because I can't find the author E-mail.
If not suitable, please remove it.

Looking forward to related functions of next release.

Thanks again.
