Important, noteworthy (7)
I believe the answer is:
salient
This clue is a double definition.
'important' is the first definition.
(I've seen this before)
'noteworthy' is the second definition.
(I've seen this before)
(Other definitions for salient that I've seen before include "Prominent, striking" , "Noteworthy" , "Foremost" , "Leaping (heraldry)" , "Entails being most noticeable" .)
