XD app - save prototypes locally on device
Protoypes tested on device must be saved locally for continuing tests even with USB cable unplugged.

We just released a new update where the latest document viewed will always get cached, and it will be accessible even if you’re offline.
TAKE YOUR DOCUMENTS OFFLINE
With this release, the latest XD document you’re viewing is always cached on your mobile device, so that if you unplug your USB cable (macOS only) or go offline after viewing a document from CC Files, your design and prototype will remain accessible on your device, even if you kill the app and open it again. The next time you open an XD document or use real-time preview via USB (macOS only), the previous cached document is replaced. With this feature, we hope your work is now ready to be tested and validated by designers and stakeholders, like a real app running on a real mobile device.

I shouldn't define this feature as 'completed' at all.
We work on many prototypes regarding many projects.
All prototypes should be kept on device, no just the latest. Why not all of them always available in a simple list until removed by us? -

This is great. However, I think this will spark the start of many more necessary ideas that people would like to have with the offline app. However, great progress.

Prototypes should be also available in a list and work without any internet connection.

I would love to have this feature!
Being able to move and show people the prototype without a need for USB cable... it's a must have feature :)

I do want to add that currently right now, using the USB cable for android and mac laptops does not work.
