and detent positioning that doesn't always seem to line up with the electrical signal transition positions.

Most I have used only pass through the transition electrically when passing through it mechanically. When the control is sitting at rest the output is always the same.

What inputs will you be providing on the submenus? When using a rotary encoder, I generally use the built-in push button to cycle between different parameters or submenus, and the rotary motion to adjust the selected parameter.

I found that I could force encoder steps just by applying slight pressure against the encoder knob without having to go through a detent click. Not at all positions and not all the time, but it just didn't have the precision feel and operation of the optical encoder I have. Like I said it could be made usable but I found them to be rather flimsy in actual operation.

The same, either a switch with a built in momentary push switch or a separate momentary switch to select the displayed menu option.

I have one encoder in which one of the transitions occurs more or less at the same position as the detent. My rotary encoder driver software has a 1-state hyteresis to make it insensitive to this. Every encoder I have purchased since has the state transitions away from the detent. The problem encoder has 16 detents/rev, whereas now I go for 8 or 12.
