I frequently switch between three grind sizes, one for a single cup, one for a pot, and one for cold brew. With the Fellow Ode I can easily count clicks to insure I'm at the expected position. With out tactile markings on the dial and a tactile arrow to line up with markings there's no way to make the grind size reproducible as far as I know. I've never tried using stepless grinders for this reason so I may be wrong about how hard it is to dial in when blind.
I think an option to 3d print a ring of dots that could be stuck to the outer adjustment dial would work, you could add a stick on dot to the inner dial and line things up that way.
From what I understand stepless is pretty common on espresso grinders. Can I ask why it would be a deal breaker?
