Presenting few difficulties in store, as yet (4)
I believe the answer is:
easy
'presenting few difficulties' is the definition.
(I've seen this before)
'in store as yet' is the wordplay.
'in' says the answer is hidden in the clue.
'EASY' is hidden in the letters of 'store as yet'.
(Other definitions for easy that I've seen before include "Gentle - light" , "Simple or uncomplicated" , "Foolproof" , "Frederick Marryat's midshipman" , "Child's play" .)
