KanColleViewer! 4.2.10: Ask Vigne Maybe
Upstream changes (fleet speed stuff). Also stuff. Ask Vigne, I guess.
Update: added a modified and updated version of BattleInfoPlugin. Unpack into KCV's folder and make sure to unblock the two DLLs in lib\ (right click, properties, Unblock, OK). This version loads the DLLs from lib\ and works fine with my default layout.
