Would in theory be possible, but might be better to create a separate app for app shortcuts, since the logic behind the scenes is completely different for rebooting to a payload or starting an app.I would really like to know this as well. I tried searching and this was all I could find. I know it wouldn't be quite AS useful, but I'd still like to have a shortcut to Tinfoil on here haha. Or maybe a shortcut to the Homebrew menu. that would be cool.
For the Homebrew menu it's probably faster to just start a random game from the main menu while holding the R button.
