I love Atom.IO and use it daily, so I wanted to make a 'pretty' theme that's more elegant than what I had been using. As this was my first theme, I decided to start from a forked version of Nucleus Dark UI.
In Atom: Settings > Install > Themes > Search for 'Sophisticated'
Via terminal:
apm install sophisticated-ui
Right now, since this was forked originally, you need to have a syntax theme that has a syntax-variables.less.
As time permits, I am working to remove requirement.
All feedback is welcome.
Here's an initial screen showing Sophisticated UI 0.2.0 with the syntax theme Sophisticated Syntax (in progress). More screens to come.
