Finished all changed mentioned by Dr. Bazuin
...
Implemented voltage-level translators for the IMU and it's 1.8V requirements; All components are now sized 0805 or larger; Test points have been fixed; all ICs that need bypass capacitors have them; etc.

Many changes and additions. Implemented most everything Dr. Bazuin pointed-out so far. Altium basically stopped working, where I can no longer search for parts, so I'm stopping for today.
