I'm replying here rather than the other thread for the sake of relevance.
I haven't decided if I will make an option for the toggle text or not. I think it's probably better to make it filterable, and then you can make it however you want.
Regarding whether most people recognize that as indicating a menu is there... I think this has been embraced as an unspoken standard in a big way.
There are many big websites and mobile apps (facebook for example) that use this symbol to toggle a menu. Two big websites that come to mind are starbucks.com and theonion.com.
I don't think it's necessarily a bad idea to add a title/label next to it though. The need for such a thing definitely depends on the audience of the website as well.
I'll post an update here when there is a solution
