Wow. Again, I should emphasise that 1Shot is developed by one guy and that the changelog above is only part of what has been done in the last fortnight alone. Kudos.
A few screens by way of illustration:
You can grab 1Shot UWP here in the Store. Highly recommended installing it, if only to watch how it continues to develop!
