I only had 1 request for the Blank 2.25u / 2.75u Shift. We don't need those. I think if we ran the following keys:
R1: Delete, End, Pg Dn
R2: Pg Up
R3: Pg Dn, Barred F&J
R4: End, 2.25u Shift, 6u Spacebar, 6.25u Blue Spacebar, 7u Blue Spacebar
R4: 6 Control (1u, 1.25u, and 1.5u), 5 Alt (1u, 1.25u, and 1.5u), 1.5u Alt Gr, 4 Windows (1u and 1.25u), and 1 Menu (1.25)
Total Keys: 28
Do you guys want the Blue Spacebars? We can bring down the costs if we omit them.
Without the mod-colored spacebar
R1: Delete, End, Pg Dn
R2: Pg Up
R3: Pg Dn, Barred F&J
R4: End, 2.25u Shift, 6u Spacebar
R4: 6 Control (1u, 1.25u, and 1.5u), 5 Alt (1u, 1.25u, and 1.5u), 1.5u Alt Gr, 4 Windows (1u and 1.25u), and 1 Menu (1.25)
