Find clues, even still (4)
I believe the answer is:
idle
'still' is the definition.
(I've seen this before)
'find clues even' is the wordplay.
'even' indicates alternate letters (even-numbered letters are used).
'find'+'clues'='findclues'
The alternating letters of 'findclues' are 'IDLE'.
(Other definitions for idle that I've seen before include "At rest" , "jobless" , "Trivial" , "Mike" , "having been taken from service" .)
