Add NOR flash chip schematic, use mini-HDMI (requested) instead of micro and add its corresponding properties and footprint, use 3.5mm CTIA headset jack with through-hole pins rather than an SMD one for extra "mechanical rigidity"

Add Proximity+Ambient Light sensor and 9-axis IMU circuits to the "sensors" schematic sheet, include the associated footprints and assign them to the respective symbols

Add HDMI schematic and connector footprint (using SMD type D/micro-HDMI receptacle)

Add built-in speaker and class-D amplifier to drive it from lineout, use an anal

Introduce a method to switch between built-in and headset microphone depending on the presence of something plugged into the 3.5mm headphone jack, included notes regarding measurements, simulations, and various findings for the headset/built-in mic opperation

Continue with the audio CODEC schematic, selected a potential STIA 3.5mm headphone jack, use logic level shifters on the WWAN/BT M.2's UART and PCM interfaces since the M.2 spec states that these are 1.8V logic levels

Add ethernet PHY schematic, assign the RGMII signals, and include its associated 48-QFN footprint

Assign verious signals such as W_DISABLE1, W_DISABLE2, WWAN_DISABLE; reorder the hierarchy to make more sense; add "solid" graphic lines around the power signals on the top sheet for clarity

Organize the USB-C, Battery, and Power sheets at the top-level such that the power-flow makes more sense when reading the schematic

Add I2C interface to WiFi/BT M.2, select an appropriate dual 2-input AND gate IC for the W_DISABLE logic and add the corresponding debounce/pull-down circuit to the HKS for W_DISABLE
