Redecorating with the Stylecatcher plug-in
In an attempt to make customizing the appearance of blogs a bit easier, I've installed sixapart's Stylecatcher plug-in. The plug-in allows you to choose from a gallery of page layouts, then automatically applies the requisite stylesheet to your blog to make it look like the layout you chose.
I'm still testing this, so I can't offer any instructions at this point, except to tell you that to access it, you'll need to go to your Templates, then look at the bottom of the screen, where you'll see a link saying "Select a Design using StyleCatcher."
I've successfully used the plugin to change the appearance of Urblog (spiffy, no? This template is "Beckett," if you want to use it on yours), but as I said, I'm still testing it. Use at your own risk!
