Phrase Freeze Option in the Phrase Pools

Hi supertonic
i am not sure about putting library and pool editor in a single window
this sounds like to me ..  might be goes to different direction than i try to suggest.
so post wasn't clear i see now.

I am very comfortable with Phrase Pools + preview template progressions very easily
( pools in Libraries... I never use/save Standalone pools  except the temporary works)
anyway ..
when i catch something good during preview (first save preview progression to phrase)
and then if i want to change some of the parts to my taste  manually
most of the time i have to copy to standalone  "Phrase" editor then freeze the figures first then change the parts

( Edit :  after changes done clear the Take ( if there) drag Figure to Take and  also to the Harmony
run recognition ...Done!  )

then drag  to pool window back.
so short of speek  I am suggesting  only  "Freeze" option in the  Library / Phrase Pool window .
