There are (Gnome I think) .desktop files in /usr/share/applications and 
~/.local/share/applications and I've devised a few that allow something 
like what I need, though I have some reservations.
For the moment, I have one called DAW.desktop with some appropriate 
stuff in it, that runs a bash script, which changes to the working 
directory and starts related applications. In this case just to 
~/Documents and audacity to demonstrate the principle. I have another 
called Programming.desktop that opens a directory ~/Programming in which 
I can presumably set up a bunch of links or scripts to location-switch 
and start applications as appropriate. I guess they too can be done as 
.desktop files.
I guess this will mean that rather than just following a menu and 
opening the workspace I want, I'll have to open he directory, run the 
workspace, then close the directory again, which is clumsy but workable.
Disappearing hovers seem not to happen when the launcher is still 2D. 
When it goes 3D, the problems start. Hopefully I can manage that by 
keeping the launcher tidy as per my question.
There seems to be another oddity with the launcher in that if I run 
applications from the command-line, rather than from the Launcher, I get 
a second icon on the launcher for that application, which again means 
the launcher clutters very quickly.
The apparently handy feature to show previews of open applications via 
Alt-tab, or double-click a Launcher Item, or Special-W only really seems 
works sensibly for low use desktops. Once there are a few dozen 
applications open, it becomes hard to tell one from another, 
particularly if they're mostly editor windows or nautilus windows or 
similar (I try to have one nautilus window with many tabs to help reduce 
clutter). A dozen little previews showing illegible program snippets is 
not wholly helpful.
Hopefully sometime this can have the filename in the hover. OK, granted 
that doesn't help much if several files are all called main.c, but it's 
a start.
Kind regards,
                      Gordon.
