Scenario:
I duplicated an app to do some major rework of the UI. I decided to duplicate it rather than modify the existing in case my ideas did not pan out - basically a fork.
The client is happy with it and I want to replace the existing app. I want to make this new one v2.0.0. But I only have the choice of 1.0.0 or 0.1.0 when creating the app's release.
