Pretty much that. I've seen it's very common for newer updates on these type of extensions to not show the artist credit info on the emote showcase once we click it. This has been helping a lot of artist so I'm not sure if it's a bug or not but it'd be nice to consider. I also noticed that I can't see custom FFZ badges from other channels nor mine, not sure if this is intentional but it is something I liked as well.
I like 7TV but taking artists credits away it's a huge no-no imo if it's intentional.
EDIT: I also can't seem to find a way to turn normal emotes to their normal 28x28 px size. I do prefer to see them this way as it's a good method to test since not everyone uses 7TV.
