The term "Orion Pro" suggests that the non-pro version is limited, and that there are more features are behind a paywall. This isn't what "Orion Pro" is supposed to be. It is supposed to just be a way to support the developers, and get some small benefits that don't really add features. It is supposed to offer:
- Direct communication with the development team
- The ability to influence the browser’s development
- Access to nightly builds, bleeding-edge WebKit (faster than stable) and experimental features
- The satisfaction of supporting an ad-free, unmonetized browser
- An Orion Pro icon to represent that support
Renaming "Orion Pro" to "Orion Supporter" is one idea.
