When someone replies to me or likes my comment, it sends me to the page with just the comment in question. If they had commented back to me there is no 'reply' button readily available. I have to view the whole 'parent comment' before I can reply. Which is redundant.

On comments that are blocked by spoilers or NSFW covers they don't show, which is fine... but then when you unblock the post to view the comment, again you can't reply right away. You have to reload the the whole page with 'view parent comment' and then.. as an added layer of annoyance the spoiler/NSFW cover is back up, even though you already okay-ed it.
