Snippets G H, and Spinner

Hi,

I'd like to suggest at some point adding G and H to the current A-F snippets memories to make 8 available instead of 6.    Two reasons:   1)  just that we can use more memories, and 2)  8 is the number that matches up well with external hardware controllers, which typically have rows of 8 pads available.

Now, actually we can use more than 8, so I also suggest some kind of spinner or other control that will let us treat A - H as banks, and so by selecting Banks 1 - 4 we would actually have 32 memories/scenes available, or by selecting Banks 1 - 8 we would have 64 memories/scenes available.
