Can I use workspaces?

With the UNR interface it isn't possible!
You have to use the desktop switcher to go in the "classic Ubuntu" interface where you can use panels.
You can find other informations here:

Hope this helps.

I would LOVE to have panels or some way to organize my open windows and applications. Any ideas?

Like I said the only way to use panels is the classic ubuntu interface, with the UNR interface this is not possible at the moment.

I actually found a way to do it. Most of the desktop functionality works within Remix, but you have to jump through a few hoops to get it. (I'm sure this could be done at the command line a lot easier, but I figured this was a safest way to do it.)

From UNR:
1) Preferences> Switch Desktop Mode>
2) Select "Classic Desktop" > Apply
From Classic Desktop:
3) Right click the Workspace Switcher in the lower right corner and open the Preferences.
4) Set the desired "Number of workspaces" to whatever you like.
5) System> Preferences> Switch Desktop Mode>
6) Select "Ubuntu Remix Desktop" > Apply
Now your back in UNR.

Here's how it works. It's a little different than the classic desktop in the sense that a) there is no Workspace Switcher and b) all of your open applications are still listed in the Window Picker in the upper left corner.

For example, if you have two instances of FireFox open on two different workspaces, they will both be displayed in the Window Picker and you can click on either one to display that instance. But if you press Alt+Tab, it will only cycle through the applications in that particular workspace.

To switch workspaces, you can either click on an application in that resides in that workspace or use Ctrl+Alt+ Right or Left Arrow. Once in that workspace, you can cycle through the applications in the workspace using Alt+Tab.

This is pretty cool because you can organize your workspaces. I like this because I might be working on a project and want to Alt+Tab between my IDE, a command line terminal, and Firefox for testing. I don't want my music player, Solitaire and the Firefox that I opened to get email getting in my way, so I keep those on another workspace.

Being able to do this in Remix makes me very happy.

You can more simply change the number of workspaces by launching gconf-editor and going to apps->metacity->general and changing the value for num_workspaces.

Or, even quicker, in a terminal type:
gconftool-2 -s /apps/metacity/general/num_workspaces 4 --type int

change 4 above to however many workspaces you want.

To display icons for only windows in the current workspace:

1/ Close or minimise any open windows
2/ Right-click the empty space in the panel and choose "Preferences"
3/ Uncheck "Show windows from all workspaces"

Thanks jfmchivall! I had figured much of that out and posted a guide on the Ubuntu forums, but your method of changing the workspaces is much easier. Thanks for posting and I have added your solution to my guide.
