I've tried out v5 and the improvements with two-hand interactions feel great! Well done.
Some small feedback for when Gemini goes out of preview:
For past Orion releases, there was a direct link for end users to download the Setup for the tracking service. This worked without needing to be signed up or anything. Lately the tracking service has only been available through the LeapDeveloperKit zip archive and you must be logged into a developer account to download it.
I think it would be helpful to bring back that direct link, because the other option is both confusing and unnecessary for end users.
