@voxman55 That is correct, you engage snapshot mode via a two button press. By default this is only done from preset mode and not stompbox mode. I was not aware of the toggle that you mentioned, Iwill try that tonight, however the snapshot system is intended to replace stompbox mode, its really a more advanced layer of presets, you are still able to treat it like it is in stomp box mode so you can adjust your snapshots.
It works as intended, for sure, the snapshot system is extremely powerful and is a great tool to have, however you can only change block parameters not the blocks themselves, this makes it very clunky to try to take full advantage of without being able to quickly switch between presets/block assignments, as this requires leaving snapshot mode via the same two button press. This is where I find myself still relying on analogue pedals in my chain to fill the void.
Your concerns regarding stage use of snapshots are valid, I am struggling to get comfortable rapidly switching between these different layers on the fly, but as with anything this will just take practice. As I think we are both suggesting, having the ability to at least bind snapshots A+B to switches 7+8, thus avoiding the need to manually open the snapshot layer would be extremely useful.
Sorry to hear they are not shipping to the UK yet, this thing is a blast, I am having the most fun experimenting with unusual signal chains that would otherwise be scoffed at... no complaints here, just things I am noticing while trying to figure out and get efficient with full functionality!
Hopefully you can grab one soon, I know I am hooked! (never could afford Helix)
