This option is not intended to be used this way.

It only skip the object instead of waiting for the start time when the begin/end time or the "dark night" is not meet. This is mostly for people doing survey like asteroid or variable stars, running a list of hundred of different target.
The documentation say:
"You can also select to skip a target that not meet the begin/end condition instead of waiting. This can be useful if you have a list of target you repeat over the night using the option Repeat the whole sequence and take the object when they are visible".

But you can trick the option to skip your first mosaic frame by adding a end time that is already passed when you start the sequence.

I must add some control to not accept this option to be checked when no start/end condition are set.

Okay, but I notice when you try to collect a mosaic over several nights, you end up with most images for the first position in the list. So the second night you want to restart with the second or third frame skipping the first. So is it not better to skip the object always if no begin/end time are specified?

Sure, but this only handle the case where a target is fully completed and you want to continue with the next.
What if you do a LRGB mosaic, have plenty of L but no B for the first frame?

I add a chapter in the documentation how I handle a restart.

For your case another simple option is to use drag&drop to change the order of the frames in the list.

The drag/drop works. :) Didn't realize this was possible. Maybe it is good to add more hints for these things. Hints are in general missing in CCDCIEL.

>>It only skip the object instead of waiting for the start time when the begin/end time or the "dark night" is not meet
Then maybe you should call it "In specified time window only" rather then "skip". Or "Time constrains", or simple "Constrained" with hint "Execute only in specified time window". I would go for "Time constrains".

>>But you can trick the option to skip your first mosaic frame by adding a end time that is already passed when you start the sequence.
If a blank time window is interpretated as time passed this would be easier and would allow using the "Time constrains" check mark as an easy way to start half way in the sequence. The sequence editing as proposed in the manual is not convenient.

Now Skip can only be checked if a time constraint exist:
https://github.com/pchev/ccdciel/commit/3b71e824ef7524b5728739ead6322f850c821481

More option to edit or restart a sequence will be done for version 2 : 0001894
