TetFuBrowser is a program that allows you to organize your fumens.
It's interface is written in a mysterious language so I can't tell you exactly what it is capable of doing. By the looks of it, you can work with fumens locally and organize your fumens in a folder structure.
There is a guide for it here but it is also written in a mysterious language and the screenshots are for version 0.17.0.0 so it might not cover newer features. http://megalodon.jp/2012-0304-1249-23/www1...p/TetFuBrowser/
You can download the latest version from here
If people can translate and figure out how this works Ill add that information to this post.
