I gave this a test, and it's unclear quite what to expect here. eg. I
create a draw document, insert a stock box shape in the top right, move
my mouse to over the top of a specific corner of that, and scroll-in.
What I'd expect (perhaps) is that the point that the mouse is over
grows large around that point, ie. that point would be the equivalent of
the center between two fingers of 'pinch to zoom' ;-) it seems instead
that what is (was) underneath the mouse moves to the centre of the
screen - is that intended ?
The origin was to fix the unintuitive zooming in Writer. Instead of zooming to the upper left corner it now zooms to the center of the screen by default. But often the problem is that when zooming in the object you wanted to see gets partly moved out of screen if it wasn't perfectly in focus before. So that's where the mouse centered zooming comes into play so the user just moves the mouse where s/he wants to look. At first I thought too that it might make sense to jump directly to the mouse position but in this case LO would have to move the mouse around otherwise the user would land somewhere else if the mouse wheel is moved more then once which is often the case. And I am not sure if it is easy possible let alone desired to let LO move the mouse around. That's why the mouse position is used as a target for shifting so the user is able to move the mouse back on its own as soon the target is focused. Right now the shift speed is static but it could be changed to consider the mouse distance from the center.
Also - if I zoom in, move the mouse and zoom in again - then zoom out
the behaviour can seem a little strange ...
IMHO we need some more UI thought / testing around this before merging
(sorry to be a pain ! ;-) hopefully there are other, easier things to be
done in parallel while the spec. firms up - and sorry for landing you
with this deeply vague task ;-)
Yes, it is not perfect that's why I have sent it to ux-advise to get more feedback. Nevertheless I think after getting used to it should work fine for most use cases (maybe after some optimizations of the center area and shift speed). Anyway I could create a patch to enabled just the screen centered zooming in Writer, which is imho the only LO app with an unintuitive zooming behavior.
