nice fonts and scrollbars in the Atom editor!

atom-nice-font.less

body {
  -webkit-font-smoothing: antialiased;
  text-rendering: optimizeLegibility;
  -moz-osx-font-smoothing: grayscale;
}

.tree-view-resizer, .editor {
  ::-webkit-scrollbar {
    width: 0.5em;
    height: 0.5em;
  }

  ::-webkit-scrollbar-track {
    background-color: #303030;
  }

  ::-webkit-scrollbar-thumb {
    background-color: lighten(#303030, 15%);
  }
}

just wanted to mention that syntax might have changed –
in 1.5 i am using

.scrollbars-visible-always {
  /deep/ ::-webkit-scrollbar {
    width: 8px;
    height: 8px;

    &-track {
      border: 0px;
      border-radius: 0px;
      background-color: black !important;
    }

    &-thumb {
      background-color: #FF7A00 !important;
      border: 0px;
      border-radius: 0px;
    }
  }
}

black / orange
