I am not sure. I think reading configuration of others is like reading
passwords of others. :) I only planned to add support for its own module
configuration. Let's be confidential and solve it the right way.

There is much easier solution in 2.5.x and I posted it several times.
Just don't use "*FvwmPager: Label" starting from 2.5.x, use a new
DesktopName command. It was invented exactly for the purpose of switching
from the FvwmPager's private data to a globally accessible data, desk
names is something that many modules and WindowList may be interested in.
Then you may read $[desk.name<n>] anywhere. Thanks to Olivier.
DesktopName 2 MyDeskNumber2
...
Exec exec xmessage "name of the desk number 2 is $[desk.name2]"
Just try currently not to use spaces in the name, because I want
to require quotes if there are spaces, currently quotes are ignored here.
Regards,
Mikhael.
