Atom's vim mode is a joke. No ex mode, you need another plugin for that ... which is kind of clunky.

Nope. Most of the code editor settings are there in the main config to be tweaked, and new packages can be installed right inside the preferences / command line.

If you have a lot of style settings in your vimrc, the ability to use an actual stylesheet (when combined with the native chromium dev tools) make tweaking the look and feel absolutely trivial.

You have to manually point and click. It's a regression. But OMG clicking is SO EASY /sarcasm
