Detector, collimator, post-tube in/out, move home/yag, the backlight button and the sample exchange/alignment/data collection transitions blocked the GUI thread for up to ~20s per move. - MoveWorker (same thread as the collection worker, so sequences and collections can not overlap) runs (label, callable) steps with a progress dialog; all controls are locked meanwhile (no nudges, zoom stays usable) - move functions raise MoveError instead of showing dialogs; the GUI shows the message when the sequence ends - abort stops all motors (motor record STOP, backlight) and ends the sequence; position checks (assert_tweaker_positions abort=) stop waiting - safety: backlight moves wait and check the position before the next step (post-tube in used to start while the backlight was still moving out) - tandem nudges stay non blocking in the GUI thread; collimator still moves X then Y - sample alignment: backlight in now also checks the detector is clear of the post-tube path (as the backlight button does) Tested in simulation and at the beamline.
