Subject: Support showing content warnings.
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=9485062c5cf107ff8891d50407934ba08ec1bc8f;p=mastodonochrome.git

Support showing content warnings.

We still don't hide the rest of the post, but this is a start, because
sometimes the poster expects that you've at least _seen_ the warning
text. (For example I saw a post today in which the content warning was
the question part of a joke, and the post body was the punchline.)

 ### Sensitive-content markers
 
-Currently we ignore whether a post is marked as sensitive: it doesn't
-show up at all in the UI.
-
-We should _at least_ display the sensitive-content tag, because it's
-not unheard of for people to use it as a post title, and write the
-rest of the toot in the assumption that you saw it, so that it might
-not even make sense without.
-
-Probably better to go all the way, and actually hide the post until
-told otherwise.
+Currently we display sensitive-content tags, but then display the rest
+of the post anyway. It would be better to (at least have the option
+to) hide the post and then be able to show it on demand.
+
+This will probably involve some kind of state object in File which
+maps post IDs to data about them that informs display. Once we have
+that, it could also be used to make the handling of unsubmitted poll
+results less horrible.
