I want to be able to drag and drop a video and have it copied to the session videos directory.
Better yet, there should just be one catch-all preference that allows you the option to copy all file types (audio, video, etc) on import. Pro Tools makes it incredibly difficult to make sure you've copied all files to your session.
It should be MUCH easier to avoid missing files in Pro Tools sessions. Especially hard drives becoming increasingly cheaper, it should be a lot easier to make sure every file is save within your session.
