Quite new to Scribus, however I think it would be nice that in my master page I could specify that left master page X is mirrored in right master page Y. The idea is that inserting a page is currently a very disruptive process.
I'd still have to move the content of the pages since I can't specify that the content is relative to the margins (see how subtle I am about suggesting another way of managing absolute positionning
) But at least, I won't have to go through 50 pages to change the master page each of them is associated with. From my point of view, doing Ctrl-A to select the whole content and moving it by 0.5 cm is relatively easy and involves less clicks then resetting all the master templates.
Hopefully, this makes some kind of sense
