Neatly arranged (7)
I believe the answer is:
orderly
'neatly arranged' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for orderly that I've seen before include "Methodical; hospital worker" , "He should leave the ward neat" , "Neat, tidy; soldier" , "Tidy officer's attendant" , "Regular - soldier" .)
