Comment 168 for bug 933776

The thing you seem to forget, Sebastien, is that the core issue is this:
A hack was introduced that not only changed the default behavior for all users, but -- more importantly -- also made it impossible to switch back to the desired behavior.

In other words, mucking around with people's configs has already been done. How about we own up to the mistake and fix it? The only reasonable way is to revert the ugly hack, and repair the functionality of 'show windows from all workspaces'. Users will have to update their key bindings if they don't like that it's working again. It won't take them more than a minute.

I can also add that I work in a corporate environment and everyone I know who uses Ubuntu here is -not- happy about the hack.
