[O] multiline agenda and/or two-pane agenda selection

[Ben]

Hi all,

I hope this isn't in the FAQ or documentation---I tried to look through 
both according to the instructions but this seems like a basic question 
so my apologies if I'm missing something stupid.

I'm starting to use org-mode and its agenda view and like it a lot.  
However, I would like to modify it so one of two things happen:

1) Easy agenda navigation
---------------------------------------

Currently I like how I can press Enter (bound to org-agenda-switch-to 
apparently) in the agenda view and it will show me the relevant spot in 
an org file.  However, it replaces the agenda view with the org file, 
meaning I have to switch back to the agenda file and press extra keystrokes.

I almost always use emacs with two windows open (tiled side by side in 
one frame).  Is it possible for Enter to open up the org file in the 
other window, leaving the agenda window unchanged?  I found the 
org-agenda-window-setup command, but it seems to govern how the agenda 
window is displayed instead of how the agenda opens other windows.


2) Multi-line agenda listings
--------------------------------------

If that isn't possible or recommended, it would be nice if I could have 
a bit more information at a glance in the agenda view.  Sometimes I 
can't tell in my agenda what a TODO item is because it's out of 
context.  For instance, if in my org file it says

    * Client XYZ
        * TODO Call Bob about paperwork
            SCHEDULED: <2012-10-15 Mon>

Then in the agenda it says:

    Monday    15 October 1012
        work:    Scheduled:    TODO Call Bob about paperwork

This is good but sometimes I wonder which "Bob" or what "paperwork" it's 
talking about.  For me I think it would be nicer if the heading it's 
under would also appear, so the agenda view would look like:

    Monday    15 October 1012
        work:    Scheduled:    Client XYZ
                                                 TODO Call Bob about 
paperwork

so I have a bit more context.  Perhaps other lines could be displayed 
too depending on the settings.


Thanks for any ideas,
