I tried a couple more skins and it's when using them that I'm able to get the alternate text color to actually work! I downloaded three free skins from HD and didn't really like any of them. I tried Storm, Rapid, and Mav-Rix and didn't like any enough to use. I liked the look of Chiclet a lot as I prefer lighter colored boards. It's a pay one but only $.99 so I sprung for it and it's pretty good. I'm playing with colors right now.
I've also got my key sizing and placement down to where it's small enough for thumb-only swiping. I'll post a couple screen captures shortly with the colors I'm testing but here's the specs on the spacing and positioning I'm using:
(All entries of for Portrait mode only)
Key size: 125%
Bottom spacing: 50%
Key spacing: 50%
Key row spacing: 50%
Keyboard left side padding:8%
Keyboard right side padding: 16%
I'm sure these numbers will change but this seems to put the board in a perfect place for my left thumb. I also opted for the dedicated row of numbers and arrows.
