[O] agenda configurable entry-text-mode

[Alexander Baier]

Hello!

Is it possible to alter the text shown for each headline after toggling 
entry-text-mode in the agenda?  At the moment, a certain number of lines 
of the headline's body is displayed.  Instead of the lines I would like 
to display the last note that has been recorded in a LOGBOOK drawer.

My scenario: I have an agenda that lists stuck headlines (no child 
headline is TODO and at least one is BLOCKED).  I record a note when 
transitioning to the BLOCKED state which gives a reason for the 
blocking.  I want to collect the reasons of all the blocked child 
headlines and display them under the parent headline in the agenda view 
(when in entry-text-mode).

Is this possible to do with what org-mode has to offer at the moment?

Kind regards,
