I agree it would be nice to have a volume readout for convenience regardless…
Pretty sure mine goes into standby and can be powered back up. I only did it a couple of times and seem to remember it’s a bit picky about where you click on the icon, and also it doesn’t give much feedback to say you’ve pressed it - but you see the amp screen coming to life. There’s probably a bit of room for improvement in the UI but otherwise I think it does what you’re asking. Hopefully someone else can confirm.
