I found myself going through 7bit's
Round 5a wiki page and found and interesting item. He has a set of keys that include the SP color codes in the key caps.
HONEYB/COLORCODES SetI thought this was a pretty cool idea. There are a lot of colors in the Round 5a series, so there's a lot of caps, but I think it'd be neat if two additional keys were included in future group buys with the codes on them. For example, just two Row 1 with each color represented. It's just text, so it would have a mold cost associated with it and you'd always know what colors were in your set.
What do you think? Is it something you'd pay extra for, or just something you'd like if it was included in the base set? Or, do you hate the idea?
