Version 1.2 is now live on the app store.
The annoying rotation "empty folder" problem is fixed and emailing is alive and well.
One oddity is that for some reason it is only showing up as an iPad app and not allowing itself to be installed on an iPhone or an iPod touch. I know this works as I tested it on both, so I'll be investigating this and hopefully get this completed by the time that 4.0 is available to the general public next week. My apologies if this causes anyone any inconvenience.
In the meantime, enjoy the update. As always, feedback (both good and bad) is appreciated!
