I've been working on the new features (analytics and custom styling) and thought an interesting way to check their validity would be to provide beta access to people who bought me a coffee via BuyMeACoffee. I had the following snippet on the analytics and styling pages:

Over the past 2 weeks I've had a few coffees rolling in. My assumptions (slightly) validated, I've gone ahead and added a paid subscription for those features.
