It would be nice if I could rename the audio files in the Pool section.
This can be done already. I do use the function periodically. The procedure is in the manual “pool” section (or I never would have figured it out).
The procedure is weird. You must click on the audio clip portion then click the file name to highlight it and change it from there. I believe this can only be done to files used in the project. Not the files in the trash folder (not sure about that as I am not in front of CB right now and I do not have access to the manual right now either.
