Use the save template to save the customized moi.css template for MGB. Use the load template to load the template you just saved. This way you can continue to tweak your design.

MGB program does not parse the moi.css file directly, which would be called 'round-trip' CSS editing. Writing a full blown WYSIWYG round-trip CSS editor which correctly parses *any old CSS* is a full-time job for a team of programmers as it would necessarily need to handle all sorts of flavors (and mistakes) of CSS. I enjoy MoI but don't have that kind of time to spend.

If you save the template, you can reload it. The background screen settings are set in the Options panel and are not stored with the MoI.css file so you shouldn't have any problems reloading the "newly generated from your old template" moi.css file.

Changing Icons could be done. I'm not sure about changing fonts as I suspect there are limitations to the GUI framework Michael uses-- especially considering WINE.
