Jscatena88's KBD67 Layout

Layout Visual

This modifies the far right column on layer 1, adds RGB control to the second layer, and creates a CTRL+ALT button on the second layer for switching between Linux TTYs (this is the key labelled LCTL(LC_L), it is actually LCTL(KC_LALT) but the visualization software didn't support that)
