At this point, it seems like the chat logs are all in one large text dump. I think it'd be rather useful to have the option to split the logs by day, or insert manual session breaks. It'd make the organizational side of things a lot easier, and dated logs are something my play group and I are used to.
Additionally, the ability to export logs (short of cutting and pasting them into a text document) would be nice, if not as immediately useful.
