I generally like Gnome 3.x, it looks good to me. But many interface elements in Gnome 3 started to use "key hole metaphor", which is awful.

For example, gnome-control-center aka "Settings" window is not resizable. For "All settings" it is not a big issue because all the items are directly visible in the window, but... click on "Notifications" item shows notification settings. There is a long list of applications there. Only a small part of the list is directly visible. To look through the list I have to scroll it. It is not convenient, I would like to see entire list, but window is *not* resizable. This is "key hole metaphor" in action: I have a huge screen but cannot utilize its space and have to look into data through small hole! (Moreover: "Notifications" have more items to show than "All Settings", but "Notifications" window is smaller than "All Settings". Why??)

The same issue appears in many other locations: long list of keyboard shortcuts in Keyboard settings, long list of users in Users settings, long list of available images in "Select Background" dialog, long list of online accounts, no-so-long list of Universal Access (but this list does not fit window anyway).

The same issue appears in Keyboard settings. Select "Custom Shortcuts", then create a new custom shortcut. "Custom Shortcut" dialog is *tiny* and not resizable.

Please let me (and other users) freely resize all these windows and dialogs. Avoid using fixed-size windows, please. Do not force us to look trough key holes.
