I developed Backspice layout as an improvement of an already great TabSpace layout. I use this layout all day, every day, at least for 8 hours. Usually doing software development using a Mac.
Backspice is an abbreviation of the 3 top buttons on the Twiddler: Backspace I Space. "I" is in the middle of the layout to allows seeing mistyped chords and helps with correcting typos. It's helps with typing without looking, i.e. while walking.
Note: Tabspice layout on this site is definitely optimized for using the Twiddler with the left hand. You probably want to create a mirror layout if you want to use Twiddler with your right hand. Feel free to submit a pull request if you create such a layout.
It's hosted on github here: https://github.com/AlexBravo/Twiddler
