I gave it a try now but don't use it anymore. Only the main menu looks good, the rest looks very very cluttered as the categories don't have any submenus and ignore the submenus set in the menu editor.
Do I miss something? There is no way to increase the icon size, there is no way to sort the entries, entries appear twice because they originally are in different submenus, there are categories with menus twice the height of the display because of missing submenus, the entry names have no description, I don't really find things in a quick and easy way. Nice try - but needs a lot of improvement IMHO. If it would be like the classic fly-out menu with its subcategories combined with this modern look it really would be great.
I'm using - no - I have installed version 1.2.0+git20140206, maybe there is a newer version which allows more customization?
