Mobile sneak quality of life improvement

It has become very clear that sneak has two conflicting functions in situations like:

Trying to sneak to the edge of scaffold or powdered snow when using either to move around a build,

Trying to shift under water to build a bridge or going back and forth looking down and placing a wall,

Trying to place intractable blocks with creative flight, you need fingers on, fly up, fly down, dpad/joystick, lookn around parts of the screen, and place and destroy,

thats 5 vs the average of 2-3

Classic controls used two sneaks to solve this for powdered snow/scaffold,

Suggestion:

The one in the middle of the dpad is Tog,

and the one that appears on the right is Tap

Tog=toggle, double or single tap

Tap=only shifts when held, allowing you to tap it

Creative flight:

Tap = fly down

Tog = sneaks you in place, same as holding jump and sneak at the same time dose

Underwater:

Tap = sink

Tog = sneak

Snow & scaffold

Tap = down

Tog = sneak

I think the way the classic controls dealt with scaffold and powdered snow is quite elegant and I’d like it available at all times and working with the new touch controls
