var NodeTypesEnum = {TAB:"tab", SAVEDTAB:"savedtab", WAITINGTAB:"waitingtab", ATTACHWAITINGTAB:"attachwaitingtab", WINDOW:"win", SAVEDWINDOW:"savedwin", WAITINGWINDOW:"waitingwin", SESSION:"session", TEXTNOTE:"textnote", SEPARATORLINE:"separatorline", GROUP:"group"};
relevant types seem to be tab, savedtab, win, savedwin, and perhaps separatorline and textnote. I guess the root node could be session, groups are actually win/savedwin and not group, and IDK what the three waiting ones are.
