After we've migrated to the new architecture and everything seems stable for a few months, I want to try creating a "web control panel"-style interface to Domtool 2. I believe I've designed the language such that this should be trivial. Specifically, I think the Domtool language's type system gives all of the information needed to generate a nice control panel interface automatically. We'd want to add some extra metadata, like cute icons for particular configuration functions, but I think it should be straightforward to implement a generic control panel that (aside from icons and extra descriptive text) builds its interface automatically from the source code of our standard library.
The gist of the interface would be a tree-editor GUI for the abstract syntax trees of the Domtool language. I think we can present it in a way such that even people who aren't comfortable with programming view it as a natural way of doing things, and the abstraction enabled by the language behind the scenes should let us blow away the competition with how quickly we can add new configuration functionality.
