Agreed, IntelliJ IDEA is so good I can't really use other editors for projects. For editing regular files outside of a project I still use vim or TextEdit/Notepad.

I prefer Intellij so much I use CLion instead of Xcode on OS X and Visual Studio on Windows 10.

I didnt think Clion worked with MSVC?

It probably doesn't. I use MinGW on Windows. Once Windows 10 adds the announced linux support I guess I'll start using that instead. :)

I can build .exe's that run fine on Windows this way and executables that run on OS X (using the X-Code supplied compiler and build tools that CLion depends on for OS X). I can get qt, wxWidgets and GLFW UIs working for both platforms from the same code base with CLion.
