[API] store Playlists and watched history

[Kenji-1984]

Describe the feature

Im a User of the project Libretube.
The data of User watched list and playlists are stored localy.
I asked the developer He told me there is no way at the Moment with the API to sync the data to the instance.

Please add such functions.

Why would this be useful to add?

IT helpes to sync the data on multiple Devices.

Playlists are not stored locally, however watch history is.

I would say this is a welcome feature by me aswell, it's the one thing YouTube has over piped that is important to me, syncing video watch progress, so I can continue watching on another device
