The auto fill-in for role for musicians and other credits is a welcome development. Unfortunately, it still has a few quirks it would be nice to see dealt with. They all concern what might be consider premature completion.

How it works right:
If I start to type "tenor saxophone", the auto fill-in completes tenor but doesn't add saxophone until I add a space after tenor. This is useful, as sometimes I want only tenor.

How it works wrong:
If I want to enter just "bass" and start typing bas it then fills in bass clarinet and I have to delete clarinet. The same works with "drums". It fills in drums and percussion everytime, even when I just want drums.
Why don't bass and drums work like tenor (and soprano and alto)?
