Mango introduces fast app switching (aka. multitasking). You can activate it by holding the "Back" button on your phone. As the name indicates, you can quickly switch between your apps. We added support for fast app switching in Genius Scan so that your scans are accessible quickly.
Mango also supports Live Tiles. What you can do now with Genius Scan is pin a document to the main screen. For instance you can easily pin your current trip's receipts to your home screen and quickly add new receipts.
