Quote from DridztWhat would make some sense imo regarding BigWigs/LittleWigs and Transcriptor is to:
1. Expose the "StartLog", "StopLog" functionality in Transcriptor to other addons.
2. Have an option in BigWigs to automatically start logging on bossmod enable for bosses that need data and stop logging on "xxx defeated" message or combat end.
http://www.wowace.com/projects/big-wigs_debugger might get us close to that. I haven't played with it and have idea if it works for 3.0 or even the new combat log stuff. If I get some time I look into this, we might be able to enable the BigWigs logging on module enable/disable, we'll see. I do like the idea very much though.
