basically, you can also limit what gets updated when the content is so
small that it's not readable...
i think that you're very welcome to work in this issue!
just take care that it's a little bit more complicated than it first
as an example, you will have to take care of text chains that go
backwards (and generally speaking of text that is written right to
in a further step, you would probably also want to implement an update
queue and some multithreading so that the dirty pages get updated when
scribus is idle (if scribus thinks that it makes sense to do so)
finally, you might only want to trigger the optimization if the number
of pages in the document is n times (where n is 3?) the number of pages
fitting on screen.
and, yes, jluc suggestion is sane, to first provide a way to know which
items are on a page and on which pages items are.
i have a naive implementation of it, that can be improved for
performance and needs to be integrated with scribus in memory model an
SLA saving. (i use it for exporting, so performance is not that
