Add a shadow under the gutter when you are scrolled away from it. This makes it easier to tell when you aren't scrolled all the way to the left.
If you want to edit the shadow, add this to your styles.less file:
atom-text-editor {// scrolled shadow.gutter-shadow.active {box-shadow: 0 0 7px 4px rgba(0, 0, 0, .25);}// bigger scrolled shadow.gutter-shadow.active.bigger-shadow {box-shadow: 0 0 10px 6px rgba(0, 0, 0, .25);}}
