[FEATURE] Indicate already seen videos

[horlali]

Description:

I'd like to propose a feature that would visually indicate which videos in a library or folder have already been watched. This would be incredibly helpful for users who have multiple videos in a folder, as it would allow them to:

1. Easily identify new content: Quickly spot videos they haven't seen yet, saving time and effort.
2. Track their progress: See how much of a video they've watched, helping them manage their time and stay organized.
3. Avoid rewatching videos: Prevent accidentally starting a video they've already seen, especially in large libraries.

I simply can't understand why people give thumb down to this, it's just stupid.

I've downloaded an 80 episode long youtube course that is not numbered, in VLC the already played videos had a check so I can distinguish between the already seen videos and the ones I haven't seen, there's literally no downside for this feature.
