One of the new plugins from MT is Stylescatcher, a simple way to apply new styles to your blog from a library. There’s a simple interface to ebale style choice andit;s obviously easy to add further libraries.
However, for me, it’snot working. On first application, when the style sheet is linked from the default library, I get no style at all. If I copy across the CSS, then I get the colours but no page layout. Which means I think I need to go and rearrange the layout, which is slightly screwy anyway, in order to use this nice plugin. Then I can do a new style every day ;o)
