Thanks for posting. I'm going to change this from a bug report to an enhancement request.

This intersects with #14356.

Switching model when moving from plan to code mode is one important seam, but I think there is also a more general control-surface issue:

  • changing reasoning depth should have its own fast hotkey path
  • the current indicator should probably be a non-semantic depth meter instead of a label-heavy mental model
  • if the user changes model/depth while a turn is already running, that selection should stage for the next turn rather than perturbing the in-flight one

Otherwise mode transitions and live control changes will keep feeling brittle and menu-heavy.
