My next big mission, by way of the import scripts I've created, is to use the imported data to help build out the default themes I'm creating, and also build features in MTL to support those themes properly.
Here's some examples of what I mean. Most of the objects available from a theme template have "next/previous" functionality. So if I say
page.next_in_category, I'll have access to the next page in the blog or the next page in the default category for that page. Many of these next/previous contexts have not been built yet, so siphoning up live data from my site and trying to reconstruct my old blogs will furnish me with plenty of examples for stimulating such work.
I have plans to create four basic templates -- see the version roadmap -- all of which are essentially extensions of or expansions of templates for sites I've already created. That'll provide me with a broad range of use cases to build features for. Those templates will be available in their own repositories, so they can be worked on apart from MTL itself. Plugins, too, will each be in their own separate repositories once the time is right. More on that in a future post.
