Thanks for your description of the problem. Very clear!

The thing that I worry about is us poor users of cheap mice lacking a 
middle button. If there a standard key/click combo for X-windows to 
get a button 2 click if you are missing button 2? (Hey, you have to 
remember--I'm used to the ol' Mac single button mice :-)

The thing you really don't address is connecting loci together on a 
single workspace and how this would work in the new button scheme? 
Would this be a button 2 click as well? It seems to me that the major 
thing a user will be doing in Loci is moving loci around within a 
single workspace and connecting them. To me, moving a loci to a new 
workspace, or even dragging it to a container is an "unusual" event, 
and this should be stuck with a more non-standard button press.

This is a very cool idea! Now we just have to figure out how to make 
the windows scroll automatically...
