I tried this back in the Windows Phone 7 days and failed due to some bugs on the phone. I’ll give it another try and see if it’s fixed in Windows Phone 8.1 for the next release. Thanks for your feedback!
Thanks for the suggestion! And yes, it’s a popular one. I personally believe that you’re wasting your time by reordering any further than using the focus button to move things to the top of the Soon list, but I will review this feature for an update. If you’re using the Windows version, you’ll be happy to know that I’m rewriting the user interface for Windows 10 to support swiping items between the lists, just like the iOS and Android versions. -David
