Let's say I'm doing a site about cars, and in the main content area of a Page (using a certain template), there are a few paragraphs about a particular car.
In the sidebar, are several standard widgets. But I also want a widget with an 'info panel' about the particular car.
So what's the sanest way of putting in a per-page widget in Wordpress? I guess ideally the info-panel could be entered via the standard page editing in Wordpress .. perhaps via the Custom Fields, so you could enter "Volvo" for the Manufacturer field and it would show up in the sidebar. (or is this something a plug-in already covers?)
