I have been waiting my whole life for this type of app! I think it is wonderful!
I am using this on a Windows 8.1 tablet/Laptop and everything works wonderfully. I have created a mediabook and shared it to an iPad and an Android and everything worked as it should.
I hope that Roxio checks these forums from time to time as I would love to know if further development is in the works. I would LOVE to be able to add my own templates...add my own text boxes, etc... I would also love many more customization options...such as more fonts, font colors, etc...
Roxio, Thanks for this app....and keep developing it!
