Comment 54 for bug 147230

poofyyoda : While I understand your frustration, speaking about this here won't be helpful to anybody as it is a bug report and it is just spamming subscribed people, asking for changes in ubuntu and/or feature, http://brainstorm.ubuntu.com/ is the appropriate place. Having this feature enabled by default created a usability bug for many users as it was too often launched by mistake due to the desktop taking the whole screen and touchpad scroll which is very sensitive. Having it disabled fixes that problem, but it does not prevent users to enable this functionnality at need. And there is patches and work to make the desktop-switcher applet work exactly in the same way then under metacity (GNOME), so what you are requesting is already in development.

>> This also relates back to the removal of the custom effects from the visual effects tab

It was not removed, just install simple-ccsm.
