I try to make my tag page more useful, as for now its only value is to show all the sub-category unfold. A good addition would be the possibility to indicate, on this tag page, which forum have unread discussions (it would also make a compromise with the traditional forum view functioning, which had this role in phpBB).
But here I have a problem : there is nothing I see in the class or ID of the
.TagTile-children a which could be used to target the ones which have unread messages.
Once we have this class or ID, we can do anything, like using bubble icons for unread messages:
Or if the sub-tags already have icons, underlining the forums with unread messages:
... or whatever, once it's CSS anything is possible.
Note that I understand well that all that would be more messy with the default tag-page layout of flarum (where the sub-tag follow each other on the same line), but it would be nice to have this possibility.
