This app is very useful, but it would be more nice if some styles are improved and made classy
This is NOT a calculator as the developer states. This is a Web developer Tool. Sorry, but it really should be renamed to stop confusion with someone wanting a CALCULATOR. My suggestion "Element Sizing Tool". Anyway good idea being a dev I can see a use for it however, I was looking for a Calculator.
