Yes I agree this makes sense. I'd like a wider review/redesign on the firmware, there is a lot of scope for improvement. I'd really like it if someone else could pick this up so I could focus on the hardware aspect, any takers?

Loading of profiles is working (no hotkeys yet).
Saving is failing... I have to read 256KB of flash to sdram then rewrite with a diff, guess that is failing somewhere.

Doh. Writing in 256 byte chunks increasing destination address each data, but not increasing data pointer! Oops! So working now, but takes 7 seconds to save (v1, v2 not tested). Not much I can do about that on v2 (256KB sector size) but could be improved on v1 (4KB sector size).

So now I can load/save settings and have profiles.

Well, I can increase the clock speed of the spi communication. I'm only at 25MHz and think I can go to 100MHz. But not sure how much time is spent in spi overhead and how much time waiting.

M25P (54MHz max), N25Q (108MHz max) I think. Thinking I should really move away from the M25P (or equiv) for v2 fix, its pretty bad. Large sectors and slow.

Added support for filtering in the file selector. Also added hotkeys to the device menu (1-4 and C).

Was getting tempted by a bigger rework, including settings in json: https://github.com/quartzjer/js0n
More work than my interest on this today!
