All Levels Navigation Menu on mobile

Are there any plans to update the way that the All Levels Navigation Menu (DDLevelsMenu) handles mobile? It seems a bit dated in the way that it works and doesn't look like most modern attempts at a slide out menu. I would like to keep using the Dynamic Drive menu system, but it needs a bit of a refresh when it turns into a hamburger menu.

I wish it would work a bit like one of the following options. Basically a slide out hamburger menu as is typically seen on the web and in mobile apps these days. But be responsive and still show the the drop down menu on desktop as it currently does.

Here are some examples:

Thanks for the suggestion. I'll look at modernizing the mobile portion of the menu in the next couple of days, at least add an animation between sub menu changes.

Just a heads up that the menu has just been updated: http://dynamicdrive.com/dynamicindex1/ddlevelsmenu/
