Some highlights in the 2016.3 IntelliJ IDEA release:
- When looking at source code the editor now adds hints that show all parameter names in method calls for literals and null being passed in.
- The debugger now allows you to examine the heap
- The Resource Bundle editor now shows you which properties are unused in the project. Handy if you have tons of properties!
- Refactoring to ES6 constructs (let, class...)
