Here's a video from December 2014 in which I talk about some of the more interesting Marlin features I was working on at that time, including the Hitachi LCD progress bar now included in Marlin 1.0.2.
You can tell I was very excited the feature to sort SD card files on the LCD controller, which makes the controller much more usable. Unfortunately, because this feature requires dynamic memory allocation, it can't be included in the main Marlin project. However, you can still get SD Alpha Sort from my fork.
