We have implemented the features in subject.
Is now possible to start in Sequence an external script / application before and after the meridian flip operations.
I also requested this feature.
I have to stop and start FocusLock when my mount meridian flips. I have been trying to cover this by incorporating separate sequences in Dragscript for before and after the meridian but with only partial success - this feature should help a lot.
Thanks very much Leonardo.
