searchDisplay: set a max width
This is made for matching the GNOME Shell Designs.
On large displays, we don’t want the search results list to expand across the whole screen; set a maximum width of 1000px. Unfortunately, since in St max-width only affects size requisition, we need a little custom layout manager to have it applied to the allocation too.
In Applications Overview the layout remains full screen. But when we type something..
The layout width changes with a max width of 1000px. My Resolution is 1680×1050 and that seems OK. In High Definition resolutions (1920×1080) which more people I guess you have or your next PC will have (even in Laptops) I am not sure how good this will look like. In the bright side, this is just an property in Shell CSS (check), so the theme authors can revert this change. They should go with a dynamic approach depending on the screen resolution, or something like 80% width.
Windows Thumbnails in Overview
In GNOME 3.8 they have slightly changed the way that Windows Thumbnails are displayed in Shell. Thumbnails are now trying to keep the original size (in scale) of the running Windows, so they make it easier for users to identify a larger Window (Chrome) from a smaller (Terminal) at first sight. Also Shell now makes a better use of the available space. It is a very nice improvement, but still missing the Overlay Icons, to help us further to recognize applications immediately.
Lets suppose we have a large application (Nautilus) and a small application (Terminal)
This is what happens in Shell 3.7.4.
The small application in preview, becomes actually bigger. That is a bug obviously.
This is what happens in Shell 3.7.4+
That is better. Of course this is work in progress, and changes and improvements are likely to come here. Success is hidden in details and GNOME is trying to close those issues.
Application Menu in GNOME Terminal
Not big deal, nothing else has changed but the Terminal has now an Application Menu.
This addition is there for some time, but I just noticed it two days ago. And that brings me again in mind that Application Menus just don’t work. The idea behind them is good, but some things just don’t work. Also application menus will never (at least not soon) adopted in applications like Gimp or Libre Office or Blender etc. Applications that are pretty popular in GNOME.
