I don’t get why most comments here are so negative. It’s Linux, if GNOME no longer fits your needs, you can always switch to another desktop. There are lots to choose from!
Which don’t mean that we cannot criticize GNOME while discussing 😉
I can agree that there could be a problem with too many windows on a desktop but the solution they propose is the worst possible one.
For a user it make no sense that when you add a window to the desktop (say open a terminal) all the other window move to other places (or you switch to another workspace entirely)
Aside the fact that usually I (and people in general) remember where a window is, the big problem is that I positioned the applications as I need and I want them to stay there because I need them that way, even when I add another one. It is my problem where to put the new window, and I will probably put it where I need it.
Put it that way: it would be a good idea if in a IDE every time you open a new panel, all the already open panels change their arrangement ?
It is just another case of “we know better than the user what the user needs” from the GNOME developers (remember when they remove the advanced option of the printers because “users would be confused” ?)
