For Horus type radios, you can add your own personalised touch to the AppMan by adding your pictures to the menu items corresponding to submenu, or replace the existing ones.
In the APPS/MENUS folder, you will find all menus and submenus. In fact, all menus can be used as a submenu, and can be nested at will. The pictures used need to be named after the menu, and should be of the png type. They will be scaled automatically to fit the available space next to the menu list, respecting aspect ratio.
On all radios, more complex, but still easy, you can change the order of the menu items. Just renumber them accordingly. Since there is no other way of knowing which file is corresponding to which menu item shown, safest approach is to change the extension of each menu item one by one, while checking which item misses from the menu. (simulator advisable :). Then, you can renumber them at will. All numbers are allowed, and need not be sequential, up til 20. Make sure you rename any existing ini files as well.
Finally, if you have the guts, you can change the menus completely. Be aware that this will only work for menu items not depending on an ini file. You can shift them between menus, duplicate them, and delete them.
If that's not enough, you can add any existing telemetry script in any menu, by just renaming it and placing it in the corresponding menu folder. They should appear in your menu, as a numbered entry.
