Question mark as Trigger icon

I think a question mark as additional option for the small trigger icon would be useful, as a question marks is mostly used on webseites as a “Help” article so more people will intuitively know that this would do. The “i” is also good but the graphic is bad at times so that the “i” kind of melts with the circle and you can’t really see that it’s an “i” on first sight 🙂
