I was just about to add your code but saw that the command for "delete" was "clear" and the addon already had a "clear" button I just never used it. I used it and is functioned just as would I expect the delete button to. So it had a "delete" after all, thanks for the reply though.
Thanks for the addon it's very useful, I've added a few buttons to it as I like to use the keyboard as little as possible and between this and the "Ring tool" by apsyll I can do that. But I'm trying to add "delete" to it but I don't know how to do it. Is there a way it can be done?
