I have no particular idea, if it is necessary to do a kind of WYSIWYG but already being able to allow access to the html code of the video description field would allow many users to make more elaborate descriptions easily
I am thinking in particular of the timed history of the videos to make a viewing plan and to make reading tags, currently the links open a new tab in the browser, this does not facilitate navigation for this specific point.
Maybe a module simply allowing the description fields of each video to be « compatible with the Markdown format which also supports custom PeerTube HTML tags » like the INSTANCE HOME PAGE field.
I found a chaptering solution on another community forum for this exact problem but it’s not ideal, I think the markdown track is a good alternative to meet all the specific needs of custom descriptions.
