Tweaking

I am a terrible tweaker, and this is probably not a good thing, because the last 5% of improvements can take the same amount of time again as you spent on the first 95%. I suspect that prolific authors never do that final 5%, which few people will notice in any case, and very sensible they are.
I've just spent about fourteen hours making a new cover for Remix; I finished last night and loaded it to Amazon. This morning I started making small but telling changes, and can't wait for the book to come out of Amazon's 48 hour publishing limbo so I can upload the improved version. I doubt anyone will notice the difference...
