I have been using Fedora 17 with Gnome 3 for a few weeks now and I wanted to let everyone know about some tweaks I have found to make it much more usable and some annoyances I have yet to solve.

Change touchpad delay after typing This has been super annoying because the default delay for the touchpad is 2 seconds! Here’s how to set it to whatever delay you want.
First, turn off the “disable touchpad when typing setting” in your system settings and then open a terminal and enter the following command.

syndaemon -d -K -i 0.3s

Change 0.3s to whatever you want the delay to be. For more info just run man syndaemon.

Install guake and other terminal shortcuts

Here are some gnome-shell extensions I found useful
Alternate Alt+Tab to cycle all windows

Search SSH connections

Alternate system menu (show shutdown option)

Removable drive menu

Maximus clone to remove boarders on full screen programs

Battery remaining indecator

Impatience to speed up animations

Helpful Keybindings
