when creating a button on tool bar, function named should be filled in automatically
that is, on the screen shot attached, if I did not ytpe in the function description "deleteAllEmail", I would have gotten some strange error message about a fn set not being defined (which means nothing to me). I tried typing into the fn box: function() { ... } but that did not work, then I put the name and it seems to have. I'd suggest putting a default name in there and let me override it if I don't like it.
This is a borderline bug, but I think it is a bug since it yields a confusing error.
As I work on this, I realize I should not be adding a function to this, but adding a click event listener (and function there). So, when I do that, I notice the events don't come up in alphabetical order. I think that's a bug also.
I knew that. I was thinking that if that is the order, then the events should be prefixed with the class (or grouped), otherwise, the listing does not make any sense.
