I often have TODOs which are not ready to do because I am waiting on input information: I have a TODO keyword called WAITING as a reminder of what exactly I'm waiting for.

Example:

*** PROJECT Report finalised
**** WAITING updated drawings from client
**** TODO Smarten up figures
**** TODO Read over once more

I have an agenda that lists all TODOs (that are actually "TODO") and what I would like is that and TODOs which come after a WAITING do not appear on the agenda.

I make this work I am happy to simply delete the WAITING entry once I have received the drawings, in this case. Or to change the layout of these entries to fit in with a simple solution.

My workaround at the moment is to not put the keyword on the last two lines, but it makes work for me then to add them back in.
