When zooming with mouse wheel, you mean?

I'm not sure that it would be a really good (default) behavior. E.g., now when 
you zoom in, you're sure that the view will keep the leftmost date, no matter 
where is the pointer. In your case, you'll have to point it precisely at the 
left border to just change weeks to days, keeping the same tasks as before 
zooming.

I think that either a modifier key or just some other way of zooming (e.g. 
selecting an area + mouse wheel) is a better way of triggering such behavior.

Normally, I have the tasks of interest in the middle of my view, when zooming 
they get lost.
Other programs (ie Visio, Adobe Reader, CorelDraw, SolidWorks, ...) also have 
this behavior (keeping point under mouse equal/stable), so I guess I got used 
to their behavior and expected this always to work like this...

Good idea. I still can not get used to zooming in GanttProject from the same 
reason - my main point of interest is in the middle of view.

i can only agree to the original post.

zooming relative to where im not looking at is quite confusing.

Hi,
great project but zooming is very "strange". As says by other people standard zoom are always mouse center.

I understand your point of view :

But is it possible to add a ctrl or alt + wheel mouse to zoom with constant date under the mouse pointer ?

Thanks
