How to make a single window on Mac OS X sticky to every desktop space?

I'm trying to make a single terminal window appear on every space but the built in spaces only allow to configure this per application basis. This makes it more or less useless for terminals if you have multiple terminal windows on multiple spaces.

DesktopManager seams to have solved this for older versions of Mac OS X.

The 3rd party software Afloat can do this. See the installation instructions:.

1. Download the SIMBL zip file
2. Unzip the file
3. Double-click/install SIMBL-0.9.9.pkg
4. Create SIMBL bundle dir: mkdir ~/Library/Application\ Support/SIMBL/Plugins/
5. Reboot
6. Install from the git repo:

$ git clone
$ cd afloat
$ xcodebuild -configuration Release install # verbose output trimmed, except for last line: ** INSTALL SUCCEEDED **
$ mv /tmp/ ~/Library/Application\ Support/SIMBL/Plugins/

Not obvious but built into MacOS.

Right click on the application icon in the dock -> options -> All Desktops
