If WTT is the search version in the main browse window, I cannot make KOR (or the Chinese Bibles) the search version in a secondary browse window (which I always use to work on verse map files). The search version in the secondary window reverts to WTT as soon as I try to scroll or switch to browse mode. If, however I do get a Chinese version to be the search version in the secondary browse window (by first changing the search version in the main window), it automatically becomes the font in the editor, which I don't want.
Whenever the Chinese versions have two verses mapped together, the second verse is highlighted (in black), making it hard to read the characters. Otherwise I've made good progress toward providing verse map files for all the new versions.
