My my...have you bothered to get into the virtual device MISC/?
"pic viewer, text editor, MC Tools, new backgounds"
Those things are already there...well, I dunno what you refer with "new backgrounds". You can't format your mc, you need an external elf file, wich I think prevents from accidentally deleting your mc files.
mp3 player...run SMS, then when tired return to ule, it has a entry at the start menu for that (you can customize the boot path in the lang file).
Running elf files with ulaunchelf in background isn't going to happen, if that is what you wanted.
