mmCalc v1.1.0 - Simple focal length calculator, I want to hear your feedback on it.

Link to mmCalc

mmCalc is a simple focal length calculator that started as a weekend project but after a lot of good and bad feedback, I'm going to continue working on and growing the project.

The latest version (v1.1.0) adds:

• Added GFX Sensor Size.
• Added specific explanation for medium format sensors.
• Performace Improvements.

The reason I'm posting this here isn't only to get the site noticed a bit more but to also hear what you guys like about it and what you think is terrible. I want to make this strongly community driven.

Also, the site was featured on Petapixel and SLRLounge, which I found pretty cool.

Any feedback at all would be really great, thanks!
