I think it looks a bit weird, I don't really care about adding a lemming to every lemmy app icon but I think something like this would be a bit more interesting.

I did that with the bonus of flipping the screenshot upside down on photoshop first. Then flipped his screen.

You can tap the comment, go on the three dots and it will give you the option to copy text. Haven't really tried but I assume it would copy the entire comment so it would probably need some editing in case you just want to cite part of it.
