Is there a way to get it to reload the customized CSS you created previously?

If it already knows the file path, it'd be great for it to load the existing CSS file and let you go from there. I made some changes but realized I made my background too dark. Unfortunately when I reloaded MoiGUI my changes didn't appear, so I apparently need to start over. I tried Load Template, but that doesn't seem to load CSS files.

Otherwise this is a really neat tool. If it would let me start to change icons, fonts, etc., it would be phenomenal.
