Awesome, thanks!

About the sharing stuff, it'd be really neat if there was a button that instantly saved a temporary PDF, uploaded it to http://imgur.com (it supports PDF upload and auto-converts to PNG and it has an API, so uploading shouldn't be that hard?) and then stored the url in the clipboard or something.
I know integrating an arbitrary web service like this into the application doesn't necessarily seem that wise, but I think that it'd be a big time saver, at least for me
This would also bypass the temporary PDF saving issue (since you know when you've uploaded the file) and the PDF to PNG conversion (since it's automatically done on their servers).

That said, I can't wait to use the new versions!
