I have a laptop with a wide screen so the dialogs are too big for me to use.So I edited it to make the dialogs smaller. It still does the same functions. I moved some things around to make it smaller.
I don't have a wii u anymore to test it myself, but if homebrews are not visible on the wii u menu I think you can press L + R + minus to open the plugin menu, there should be an option called "homebrews on wii u menu" or something similar
