Would be great if the normal view cube lock could be used for that.
Having a true 2D pan/zoom in lock mode is still my #1 Nomad feature wish by far (mostly for working with reference images, but for 2D curves like this it would be useful as well)
Would be totally cool indeed. For a mouse user on a desktop a no-brainer, in Nomad it’s extremely difficult to have control over panning or zooming. You always mess things up.
