I apologize if this is a duplicate topic, but I couldn't find anything.
I can honestly see Gnome Shell's extension base surpassing Compiz in terms of both productivity and glitz. As things slow down and stop breaking so much, I imagine we'll be seeing a much larger number of available extensions. After sanderd17 showed off a new Trailfocus-style extension, I'm more convinced than ever. So what would be your top hypothetical Shell extensions?
Here are mine:
gnome-shell-extensions-i-have-a-keyboard-dammit - Navigate the shell with the keyboard.
I'm aware of the windows navigator extension, but it's fiddly beyond reason. At default, the shell is largely deaf to keyboard commands of any kind. In the Overview, I'd like to see Up Arrow and Down Arrow (by themselves) switch workspaces and Tab and Grave cycle forward and backward in the window list.
Alt+Tab is inconsistent with the way the rest of the shell works, but it's also a needless addition when the rest of the UI is driven from the Overview. It would be preferable to be able to navigate the shell the same way whether by mouse or by keyboard.
Enter and the arrow keys would also work as expected in the Shell's notifications and the like. At present, they're simply ignored.
gnome-shell-extensions-animations-add-on - Expand existing window animations for a seamless UI experience.
Nothing fancy, but I'd like to see a few more, and more consistent, animations for windows. (The Shell's own animations can be configured through its theming.) At present, windows come into being in a very pretty fade, but vanish suddenly when closed. Then there's a pretty minimize animation that's not even used in the default experience and could well have been used for closing, too. I'd like to see fade animations for quitting windows, as well as when switching tasks between overlapping windows.
gnome-shell-extensions-synapse - Replace this bloody worthless search with Synapse, because it's awesome.
Okay, maybe not really, but I'd like to see the Shell search replaced with something like Synapse. Synapse can run shell commands, search recent places and documents, search Wikipedia or Google, and even control media players all in one place, without ever touching the mouse or trackpad, and it does all of it lightning-fast. Unity's search is very similar, with almost all of the same features, really taking advantage of what Zeitgeist offers.
The Gimme extension for Shell doesn't come remotely close, and Shell's current search feature is just a (painfully slow, but that may be unique to my setup) filter for the applications menu with a couple of clickable-but-not-keyable buttons added for Wikipedia and Google. (Reasonably, the search already has you typing. It shouldn't require the mouse.)
gnome-shell-extensions-animations-transparent-menus - Make application and right-click menus slightly transparent.
What do you want to see happen in the wild and ever-expanding new world of Gnome Shell extensions?
