Feature request: Not watched playlists

[bastafidli]

I am wondering if there is a customization with this feature or if not what is your opinion about this feature.

I have several import directories each with many subdirectories to which I am continuously adding clips. Now I have to browse through each subdirectory to see where I have clips I have not watched yet. I would like to see a flat list of clips I have not yet watched per each import directory. This playlist would work similar to Now playing playlist. When Sage discovers clip which has not been watched yet, it would automatically add it to the Now watched playlist for that import directory. If I watch the clip or if I toggle the watch flag, the clip would be removed. If I turn the watched flag off, the clip would be automatically added to the list again. This way I would need to only go to a specific playlist for the desired import directory and see all the clips which have not been watched yet and choose the one to watch.
