In the Fit Model Platform, under Effect Summary, one can remove and add effects.
btw: Is there a Shortcut to undo the removal of an effect ? (Ctrl Z doesn't seem to work)
And is it possible to "disable" an effect ("remove", but keep in the list, e.g. crossed out or grey).
The idea:
after removal of an effect, it takes some while to bring the effect back into the model. (and the user has to memorize which one).
With the possibility to "disable" an effect, one could play with the report without big harm to the model.
