I suggest to check every parameter of your favourite presets and find out for yourself what works best, or what is the "key value" in a preset. This can be a lot fun and you'll get to know your pedal a lot better. But it takes a lot of time, too.
I think it's a lot of work to create this kind of preset guide. I'd rather have the developers work on software improvements like the much needed preset naming thing instead of taking up time to write a guide that is not absolutely necessary.
But these are just my $0.02 :))
