You could save the current location and return to it. Handy during the alignment process. It would be very handy to be able to return to a specific stepper location corrected for sidereal rather than a coordinate. Reason being that a coordinate can be affected by alignment mistakes. Initially a single bookmark would be fine and we can start with a coordinate as it would be simpler to add. The bookmark could be stored in the ini file but it's not required. It's meant for short term use.
