Is it possible to edit and preview Shopify Liquid code without using Shopify?
<p>I'm starting to use Shopify and am using a theme on Shopify and was wondering if I could edit a theme outside of Shopify?</p>

<p>My reasoning is, I'd like to use Livestyles (App that let's you preview changes instantly) but if that doesn't work, at least I can refresh faster.  Right now, previewing changes takes a little longer than I would like.</p>

<p>I know you can export the theme, but what about editing and viewing it?
My real question is how do developers customize themes?</p>
