Readdle has announced new details of PDF Expert 5, slated to come the first month of December for the iPad. The major upgrade will sport an all new design, completely new file manager with drag and drop functionality, colour tags, favourites, background downloads, Windows Shares (SMB) support, a new PDF viewer, AirDrop and more.

They also make sure people know this is an optional upgrade and mention PDF Expert 4.7.2 is still great and will be maintained for the next year. PDF Expert is a fantastic app and those who sign and create contracts use it all the time, such as realtors.

This September, the company made the app a free download as a promotion.

The company says PDF Expert 5 will support iOS 6 and iOS 7, and run on the iPad 2, iPad mini and any retina iPad and debut at $9.99 as a new app, which they spent a year developing. You can learn all about the new details here.
