4x4x4x4

4th time solving 4^4, first on keyboard, first timed.
I find hard do the slices move, my thumb refuse to leave spacebar or hit random buttons, I hope I'll get use.
Solve is pretty bad, I'm not 100% sure that this triplets generalization work for solving fast. Building the 1x1x2x4 "walls" is difficult due to high number of pieces to recognize, the 1x1x1x4 "lowbar" is istead pretty straighforward.
I will probably try to switch to 1x1x2x2 center + 3 1x1x1x2 edges + 4c corner.
