Creating a UI on a microcontroller: Part 9

I finally got this library knocked into shape enough that I could start porting my application to it. Doing so showed up even more shortcomings but I've now fixed this and we're back into feature creep.

The application pretends to be a 'computer terminal' and needs to deliver movie style retro computer interactions. Once of these is looking at files stored on the SD card attached to the microcontroller. Which will sync across multiple 'nodes' running the same code.

I've spent a chunk of time this week improving how large chunks of text (or small files) display and have added support for basic Markdown formatting. You've limited capabilities in a dumb terminal but I think it does well enough at stopping it being a wall of uniform text.

Here's a quick video demo of the user interface in action. It can be driven entirely with keyboard but also the mouse works and you can click the buttons, scrollbar on the text window and so on.
