This is a meta issue for features which are available on YouTube if you are on a channel but missing on Invidious

• Profile image

• Profile banner

• Users startpage on /username/featured

• Community (e.g. https://www.youtube.com/user/BBC/community)

• Channels, Featured channels (e.g. https://www.youtube.com/user/BBC/channels)

• About (e.g. https://www.youtube.com/user/BBC/about)

• Subscriptions (e.g. https://www.youtube.com/channel/UCdixTz20ffzqXLHxCRtO5IQ)

channel search is also something very useful

[omarroth]

Channel search is supported using channel:UCID syntax. Although would probably be made more user-friendly with #179.

Added banner and thumbnail with 0d0d3ed.

Featured channels and information provided on the "About" page is already provided in the API, so adding it to the channel page should be fairly straight-forward.

[omarroth]

Added communities as /api/v1/channels/comments/:ucid with 196ee1a. Similarly to the above, should be a mostly straight-forward addition for a "community" page now that support has been added to the API.

Added community page with bcd239a.

i get an error when opening this page https://invidio.us/channel/UCLLibJTCy3sXjHLVaDimnpQ/community

@elypter this bug got fixed with af592ea

I have added "Subscriptions" to the features list in the first post

[omarroth]

Added description with f71d5c4.

[Perflyst]

I do not think we should mark "About" as done. There is also Details, Links and Stats available
