my ideas:
-start usbhost or nethost via vshmenu (idk why but can it be useful?)
-mount usb mass storage device via vshmenu (not having to click on usb connection. just plug and go)
-subfolders for game menu (homebrew, back ups, emulators, etc.) if possible. (when going into memory stick under game you see subfolders and you open the folders and see the applications. like in memory stick under photos and music you can add subfolders.
-autokernel detection.
-ability to change colors of recovery menu (? possibly put a custom back ground ?)
-ability to change button trigger to access recovery (ability to change that through vshmenu as well)
-enable or disable recovery menu at start up (when turning on psp the recovery menu shows up automatically if enabled. if disabled you have to press a button to get to recovery menu like always)
i know its a lot but im just putting the most i can think of at the moment so i dont forget later.
