List of things to be done (6)
I believe the answer is:
agenda
'list of things to be done' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for agenda that I've seen before include "List of items for discussion at a meeting" , "Matters to be addressed" , "Something perhaps hidden" , "List of items to be discussed" , "things still to be done" .)
