[FEATURE] Caching of user filters (YouTube section)

[VeckoTheGecko]

Describe your suggested improvement
Caching user filter selections to local storage would be helpful for users who revisit the Knowledge Hub often.

This is particularly important for the YouTube section (#15) where users may revisit the feed regularly and want to see a certain subset of channels.

Would you be capable/willing to implement the improvement?
No. Someone else can take the torch on this.

[VeckoTheGecko]

Shifting to high priority as we now will have many more YouTubers in the feed, and could get annoying to manage for people if they have to configure their filters every time they visit the page.

@VeckoTheGecko thinking just localstorage like which colour mode?

[VeckoTheGecko]

@dmlb yes, localstorage would be great for this
