Ability to make filter offsets relative to another filter

Hello Jared and Ken,
first, thank you for your previous reply,
I would just add a thing concerning the filter focus offset. I realized this night that the focus offset did not work because I have not clicked on the 'set focus for ..." button. I have well imported the offset values from the filter wheel driver and I thought that this was sufficient, but not .... ok I have not read this precise part of the SGP instruction, as this functionality appears to be evident, in addition if you re-install every night your telescope you do not want a 'rigid' absolute mode and you believe that the instruction 'successfully' imported from the FW driver will work.
May be it would be a good think to just made a warning to inform the lazy users, like me,
that SGP works with an 'hybrid' filter focus offset mode, that the offset entered in the fw driver are not used as such and that the user have to choose an absolute starting focus position to make SGP working correctly.
Thank you.
Pascal
