at the moment, it's not a feature I use a lot.
I find it a little 'hit & miss'. It's difficult to fine tune expressions with this method, as it seems to happen all too fast, and the method of controlling the expressions (using the mouse) is a little random. Also, I may just not understand how to use the feature properly, but from what I can see, once you've recorded a motion using the puppeteer method, you can't go back and correct or fine tune a section using the edit mode. From what I can gather, you either use the puppeteer mode OR the edit mode for a given section of the timeline. You can't for instance record a section using puppeteer mode, and then go back to specific time, and edit just that one frame, using edit mode as it appears to be ghosted out.
I'm finding I'm primarily using the edit mode for this reason. It's a much longer process, but allows me a much more accurate method of animation. Although I still think the puppeteer mode is good to have as an option, however it would be good if you could go back and edit the recorded puppeteer mode animation using edit mode. Maybe you can ?? But I can't figure out how to do it...
