Thanks mydanilo! I knew I could count on you for feedback. These changes actually took some effort - so the comments are very appreciated!

Re. adding info to customer email. The admin email already has core functionality to include that kind of information. I just had to correctly piggy-back on it. To change customer email templates might require changing core files or templates - and that is probably not a good idea. The addon has to work standalone with no code edits or core file changes (IMO).

Re. adding credit card type. I agree! I was actually trying to do that before just putting 1.7 out there. But it is, obviously, just a little easier said than done. It is doable, and will get done. Just depends on how much effort I can spend in the next week or so isolating that info, and putting it with the Auth data. But I will do it, and if I get it done sooner, I'll make it available to you via direct download as I'd like to wait on publishing new versions until there is more to do.
