Suppose I am a Photographer. I would like to have all photography related apps on desktop #1. Then again I am also a musician. A second Desktop would have all Music related apps on the desktop #2. Then , to make life easier I would have all my Utility programs on desktop #3. Do I have to go on ?
All this is wishful thinking, as long as it is not possible to have the selected apps on the dedicated desktops. with only the pertinent icons showing for instant access

I seem to recall that some time ago a post showed how this can be accomplished via command line manipulations. The search function on this forum could not retrieve the post.
