One of the 'issues' with scripting is the risk in getting out of sync with the Magic Lantern updates.
I've therefore revised the Focus Bar and Toggler scripts to be in sync with the latest (as of today) Lua Fix Experimental branch, which is the Build dated 2017-12-03 22:09 at http://builds.magiclantern.fm/experiments.html
I've also withdrawn the links on the right to my other scripts, but will add these back as I bring them in sync with ML.
The Toggler script has been written to work with the Focus Bar. That is you can use Toggler to switch the Focus Bar on and off, as well as switching the FB focus stacking feature on and off.
