Set Mark Read setting by folder/feed
For example: I want my YouTube folder to mark an article as read on click while the other folders should be marking articles as read by scrolling through it.
An another option is to add an ""on scroll & on click in mosiac view" Since i use that view for YouTube. But i see that would clutter the "Mark on Read" list pretty easy.
Looks too complex, not yet sure about it.
Perhaps you could try to use "on scroll & on click in list view" option and set YouTube to list view (although it's not the best mode for YouTube). Or you could star/tag YouTube articles you want to watch later.
