zooming in/out at any user's move? is it good or bad?

[Vitorio Okio <ovitorio hotmail com>]

I was preparing this as an answer to "nodata" in "multiple desktop 
usability" thread.  But then decided to open a new thread instead, as I 
feel this is important.

I think a discussion "are multiple desktop good or bad" is absolutely 
fruitless.  For some of us they are indispensable, others never use them. 
This is a simple matter of preference. I personally do not use them. But 
again, never mind this.

The problem as I see it, is an excessive and mostly absolutely 
unnecessary zooming in/out of the entire screen. No matter does one uses 
multiple desktops or not. 

Even if one does uses multiple desktops, why would he want to zoom in/out 
his screen every time he needs to get access to a menu, to a search bar, 
to a recent documents list, to an icon in the most used apps, etc.?

For heaven sake could anybody answer such a simple question?

Another question... If I go to a search bar, to a recent documents list, 
to a menu item, does it mean I want to see Activities Overview?  No, most 
of the time I wouldn't care less.

According to the GNOME Shell design documents it is supposed to address 
"...problems of Focus, Attention, and Interruption"

I cannot imagine anything more obtrusive and disruptive as the Activities 
Overview get open and taken a good portion of my screen, and the entire 
screen zooming out, each time I want to get to a menu, to a search bar, 
to a recent documents list, to an icon in the most used apps, etc.

I might sound silly, but I want the Activities Overview open only when I 
want... Guess what?..  ONLY when I want to Overview my Activities.

I might sound silly, but I want my screen to zoom in/out ONLY if I do use 
multiple desktops, and ONLY when I want to see them all at once.

Again, IMHO, GNOME Shell today in this part contradicts to declared goals 
of its design document.  It is uncomfortable to use, and is targeting 
only one specific part of community users.  

But even this part of the community users will soon get sick and tired of 
the screen zooming when there is not any need for it.
