I as thinking about having the tags set in the sections of the 
appropriate options and I ended up with no good place for the UI strings 
which lead me to create the second item. Good idea, lets simplfy it as

I will remove them (where I wish that the Gamma option would not be 
removed, as one can quickly correct too dark or too light output with it).

If I use number-up or fitplot with PostScript, PDF, or image input, will 
the margin settings not be used then to determine the frame into which 
the pages get scaled?
