manual for ipad version of ampiltube?

[qbbenub]

I can't seem to find a way to actually save a preset using amplitube cs/4 in my ipad. I have no problem on my desktop, but there seems to be no option such as file->save anywhere. I can create a preset category, and enter a new preset name, but no way to actual save anything to that preset. Im happy to rtfm, but find no manual anywhere to do that with. any suggestions?

so, I figured it out - hold down the preset button! still would be nice to have a manual, wiki, whatever

and yes, there is a "manual" under the help section of the menu bar, but that just barely scratches the surface. Like, for instance, is there a way to disable all cabs in Live mode?
