I just thought of a few more questions.
Any chance that the stand alone vim key could be upgraded to a kit?
Containing the spherical key and the VIM, VIMCAPS, VIMSTEP cylindrical keys in the same white and green colors.
Seeing these RGBY kits I wonder if there could be something like CHERRYRGBY10X?
Now that we got the 3rd row control key, could there be a red one matching the control in CHERRYRGB10x?
I guess most of this only is my wishful thinking. But please prove me wrong

Edit:
Oh one more. Some language kits appear to include the ISO enter and short left shift. Like the UK kit.
But the SE kit don't show these in red. Is they not included there?
