I guess that depends on your way of work, and the files you're working
on. Personally, what I dislike about single page view is the abruptness
when I go from one page to the next. Of course this doesn't apply to
But all in all, I guess it's a matter of taste, so both single page and
continuous modes should be supported.

Marquee zoom has already been implemented and works quite well (up to
"insane" magnifications of several 10000%).

This is implemented.

I looked into it a while ago, but it doesn't seem to be straight forward
with Qt, owing to the fundamental differences of window management

Would a measurement tool work as well? For starters, this could be as
simple as showing the cursor coordinates somewhere in the status bar,
but could be extended to measure, e.g., the length or angles of lines.
Rulers should be doable as well, but their implementation is probably
not straight-forward when in continuous mode (as different pages may
have different sizes and orientations) and possibly not very helpful on
some cases (e.g., when wanting to measure something in the center of the

Of course it does. Marquee zooming is no different from "normal"
zooming, you only specify the final zoom level and center point
differently. So only your poppler implementation is the limit ;).
