I've just uploaded a fixed version. If you could check it out and report if you find any more issues or not, that would be cool. Then I'll wait before I tweet about it.
Wasn't a big issue, just the function from a plugin not working on Linux for some reason. It gets all the engine toggle widgets, so you don't have to put them one by one in an array. That's an odd thing that there is no builtin function for this.
