Since the blades in MC360 were not as easy to configure as I hoped, I started searching for some other easy-access-menuus. Ofcourse the SubPanels (or whaterver they're called) are easy menuus to configure. Once I noticed that MC360 doesn't contain DialogSubMenu.xml I could easily edit that file and add it to MC360 in the PAL map. Since DialogSubMenu.xml is connected to SubMenu (read: XBMC.ActivateWindow(SubMenu)) it was easy to implement it.
I now have a menu with custom buttons. I made a scripts menu of the panel but ofcourse you can do anything with it.
I filled the whole menu with buttons and set some to be invisible. Set <visible> to 'yes' and you can use them. This also goes for the Dividers.
For easy use I added the <four> button in Keymap.xml and connected it to XBMC.ActivateWindow(SubMenu)
Note: some buttons are already filled in and direct to my own scripts. Ofcourse these buttons will not work while you haven't installed the scripts yet.
