Visual Studio Code is looking to be my new text editor of choice for small to medium text wrangling. It's free, fast, has an extensive extension library growing for it, and I can even do TypeScript, Node.js, and PHP debugging through it should I desire. It plays really nice with the .Net Core 1.0 stuff and I can launch things from the terminal/command prompt as well! Oh yeah, you can get it for OSX and Linux as well as Windows. Kudos Microsoft! Keep it up!
