The imaging plan defines a set of exposures that you want APT to take.
In order to provide better control and more clean user interface, the Plan Editor has different look in DSLR and CCD/CMOS modes. Also APT keeps separate sets of plans for the two modes. See Select Camera Type section to see how to change the mode.
A plan which is in running execution can not be changed, there is no problem to edit the others.
