No, not really, and the Command key idea makes sense -- I just have to make
sure it's doable with the current event code. I think it is, but I don't know
for sure, so I'll look at it. Note of course that layout is still top priority
for 9.3.0, so this might slip for 9.3.1 if I can't figure out a good way to
do it, but I agree that such a feature would be useful.

For everyone who did not follow our private mail discussion about this:
The idea was to be able to handle mails without the need to load them in the 
"view pane" before. If you have a huge size of mails to sort, or several big 
mails, or if you just have spam to move to the trash or spam folder it is 
annoying that every single mail gets loaded before you can move/delete or do 
anything with it.

Looking at this to see if it was a simple tweak I could make for 9.2.3, this 
code already *is* in Classilla/Mozilla 1.3.1! Under 
msgMail3PaneWindow.js::TreeOnMouseDown(), if you right-click, it triggers this:

    // Detect right mouse click and change the highlight to the row
    // where the click happened without loading the message headers in
    // the Folder or Thread Pane.
    if (event.button == 2)
    {
      gRightMouseButtonDown = true;
      ChangeSelectionWithoutContentLoad(event, event.target.parentNode);
    }
    else
      gRightMouseButtonDown = false;

Mathias, is there a way you can try this to verify it works?

That one workes quite well. If I use "crtl - klick" I can use the popupmenu 
appearing without getting the messages loaded. BUT I still cannot mark/select 
them and use the drag&drop possibilities. That works only for the popup menue. 
A improvement, and good possibility, but maybe you can change the next click to 
let the message selected as well?

That would mean to implement all the normal drag&drop possibilities after 
someone did a "crtl - klick" and a 2nd click. And for returning to n"normal 
mode" a 3rd klick. Or you could change it to "crtl - klick" for selecting 
without loading, and "crtl - klick" with holding down the mouse button for 
appereance of the recent popup?

Let's see what we can do with this for 9.3.1 also.

Hmm, this is going to be more involved than I thought. There isn't direct 
support for this in the code, besides the fact that JavaScript can't detect the 
Command key.

Dropping for 9.3.1 because I can't find an easy way to feed Cmd to JavaScript. 
Have to think about how to rejigger events.
