[Feature Request] Navigate file browser with dpad

[deadpahn]

I got this idea while auditioning a folder with lots of samples. It would be nice to have a way to scroll through the file browser window and audition samples using the D-pad. Tapping is fine, but when looking for a snare that fits your song in a folder with 40 or so samples, it can be annoying to tap through the list. Could we possibly allow loading samples via a button during this D-pad navigation mode as well?

This is actually a little trickier than it sounds, because the widget library tobkit has no concept of "focus".
