I did not know how to « title » that, sorry.
In icon task list, if you have more than one workspace, right click on running app’s icon shows « only on this workspace » by default and you can choose « always on visible workspace ».
First issue :
- you have to do it twice before the check button displays accordingly.
But it works, use workspace switcher applet and see calc always on screen. But…
Second issue :
- as soon as you use Ctrl+Alt+ → or ← the check button goes back to « only on this workspace » although the « always on visible » feature still runs ok.
…now if you want your app’ back in « only on that workspace » you have to quit and relaunch it. And…
Third issue ( or my misunderstanding ) :
- switching workspaces with ctrl+alt+arrows keyboard shortcut ends with more than needed workspaces. Let’s say I did not get how that « add workspace » feature works, explanations welcome
