I decided to move Space back into MOOO position from LOOO as it's faster to press MOOO and Space is used 5 times more than "s".
I originally moved Space to LOOO on 9/26/2014 as I was using Twiddler2 and noticed that when I press the Space after "and", "ing", "for" and other MCCs, I often do not see the Space. I believe this problem is fixed in Twiddler3.
So I swapped "s" and Space. It works correctly, the Space is not swallowed after "and" and "ing".
I was considering moving "s" to some other place since I need to learn its new location anyway.
But "s" is 4th most frequently used key, so I'm leaving "s" on LOOO.
The learning curve of this change is something that has stopped from doing this earlier, but I believe it's worth the effort.
