I know this has been discussed before, but don't think anything has been done about this. Really important to be able to convert markers with duration to a subclip or to mark an in and out reflecting where the marker resides and the duration.
This was simple to do in FCP7... and was enormous timesaver.
And would be great if you could use the tab key to navigate from name field to the duration field.
I'm sure others have more ideas about improving this feature set.
Thanks as always to the Premiere team for a great job...
