If you are working on a document with multiple pages and you zoom out, it should
go fine.

But if you want to zoom in to get back to the spot you were working on,  or to a
newly selected passage, you can forget it. You will be zoomed-in at a mostly
random passage of the document.

Sometimes you'll end at the beginning of the document, sometimes the "middle" of
the zoomed-out view (when in Single page view), sometimes at what seems to be a
random position in your document (automatic or columns view).

This erratic behaviour while zooming-in happens while zooming with the zoom
slider, or with CTRL + mouse wheel, or when using the dropdown list in the toolbar.

These jumps are very annoying when working on a document, and really disturb the
workflow.

Proposed solution: when zooming in, the cursor position (or the current
selection) should always stay within the view, so that the user doesn't get lost.

If the selection is huge (for example on many pages) the beginning of the
selection should be always visible

This is a complex problem, and has no really perfect solution, but almost
nothing could be worse that the current erratic behaviour.
