Just want to throw this out there - the standard navigation column on the 65% layout is 4 keys top to bottom. Maybe I'm alone on this, but I actually use all of those nav column keys.

Nothing personal, but I hate that so many KB designs just willy nilly drop 1 or more of those keys. I mean, I see that you have a fingerprint reader, but there are, not exaggerating, 20 other keys on this layout that I'd rather see dropped first to fit in a fingerprint reader, logo, badge, etc. There are so many boards I've passed on because they prioritize other stuff over the basic functionality of having a complete layout. Yeah, it's just one key, but that's a key I use daily.
