Electron was also not extracted from Atom - it was always extracted as atom-shell. It was just rebranded as Electron. Atom ≠ atom-shell.

No, a subset of Chromium is bundled with Atom: https://github.com/atom/libchromiumcontent

0.116.0? That's an ancient version (or a typo). You should probably upgrade to 1.0.

In part, this is because VS Code is currently not extensible at all – there is no package ecosystem, and therefore no vector for users to possibly introduce instability / performance issues.

You don't have to guess about the startup time – you can find the actual startup time by searching for Timecop in the Command Palette.

Just add Inconsolata to your Font Family in Settings. If you want the old font size and line height too, set those to 16px and 1.3, respectively.

VS Code is not based on Atom - it's built on Electron, the app framework Atom is also built on, and uses some of the same Node packages Atom developed.
