Of no special importance (7,4,3,5)

I believe the answer is:
neither here nor there
'of no special importance' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for neither here nor there that I've seen before include "Where we find the Scarlet Pimpernel" , "Not relevant" , "That's of no consequence" , "So somewhere between" , "In transit" .)
