In building a Tumblr theme I've got an external .css on my server which is very convenient because I can work directly in my editor, save to my server and refresh to see my results.
However, if I need to make changes to the HTML of my theme I've been making the changes in my editor, copying everything over to the "Customize Theme" option in Tumblr, then having to save there. This is really tedious and cumbersome because of the way their editor is laid out (the html covers the entirety of the the preview).
Does anyone have a smoother workflow? Even if it involves just viewing my .html directly from my server when tweaking, then pasting it in when done. Like some way to inject test content so it's not just the html template tags?
