Can you Rearrange Wii Channels?

Is there anyway to rearrange Wii Channels?

That is, can I put my ‘marios’ together on one row, my donkey kong countries together, etc, on the main screen?

You sure can- just hover your cursor over the channel you want to move, then press and hold both A and B, and let them go when you’re done. I personally sort them by system (NES, SNES, N64, GEN, TG16), and then in alphabetical order by game name.
