ShogiBoi

ShogiBoi is a tool for organizing Shogi game records (kifu) into collections in a single file (.kco).  You are able to tag your games, as well as search by those tags,  preview games before you copy/paste the raw .kif and even search games by position using a SFEN string. The ShogiBoi program also detects positions, which allows auto-detection of certain castles and openings. Currently, the list of recognized structures is quite limited, but it will grow as development continues.

Included is some documentation and some example kifu collections with tagged games and tsume problems
