Anyone tried Visual Studio Code? It's a modern open-source source code editor... that only has VS in the name. Looks a lot like Atom (which I haven't tried yet.)
It runs Linux, Mac OS X and Windows. Also... I'm gonna say it again, it's open-source!
Very very space efficient. Supports terminal-like commands for doing stuff like typing a one-liner in to install an extension--of which EVERYTHING is a modular extension. Language support/debugger, themes, highlighting and intellisense, source control, everything.
It uses hotkey commands, as well as that terminal language, for everything. It's super simple yet somewhat daunting at first. There's so much "new" stuff in there that I'm probably going to have to sit and watch a 10 minute video to really understand the ebb-and-flow of it.
But it definitely feels like its from the future / where IDE's will eventually lead.
Contrast it with Visual Studio's WALL-OF-MENUS and EVERY KEY IS A HOTKEY mentality. Then again, at least Visual Studio is the one Microsoft product that hasn't become Metro'd or Ribbon'ified. God, Outlook, Excel, CRM, and half their products are a steaming pile of dog turd in terms of productivity.
