LightTable instructions

Create a css file somewhere, in my case /Users/prokopov/.lighttable.css:

.CodeMirror { text-rendering: optimizeLegibility; }

Open LightTable, press Ctrl + Space, open Settings: User Behaviors.

Add this:

[:app :lt.objs.plugins/load-css "/Users/prokopov/.lighttable.css"]

Save, changes should apply immediately.
