Ross Jacobs (ID: 00000006ab3776b5) Voted 2 ★ - Updated 09/06/2019 It is unclear what this does. These are some questions I have: * Which company's licensing does this calculate for? * Why do I see conditionals 8 levels deep? * Why do I need to login/register to use a calculator? * Why do I see this code snippet in popup.js? Like why would ever have an if(true){ conditional? if(true){ if(true){ * When I go to https://license-calculator.herokuapp.com, "private" is misspelled Sharmarke - You need to provide better documentation and improve code quality for this extension, regardless of what it does
