I wanted to say a couple of things regarding folder's next version.
First, I plan on getting email integration taken care of and implemented. If all goes well then this will be added in the next release.
With the changes in iOS 4 it will now be possible to make Folder for the iPhone/iPod touch. I will be doing this in the next update as a universal app. This will allow existing folder users to also use Folder on their iPod touch or iPhone and new users to get it for all platforms as well.
Additionally the icon has changed slightly since 1.1 and will be updated with the next release. Thanks to osxmagazine.com for the icon help!
Suggestions and criticism are welcome. Thanks for using Folder!
