I like using the Adjustments and Effects feature to fix some video files, like tuning contrast, colour, etc. The only problem is that I have to redo those adjustments every time I want to watch that video.
I think it would be nice to be able to automatically save and apply adjustments made to video files so that they take effect every time I load that video.
Edit: In addition to this, saving the volume level per file would also be nice.
