A Little Trouble with Reply Comments

Playio's reply comment feature only shows the username, not which comment is being replied to (like a single-level thread? I don't know if anyone understands what I'm talking about lol). Sometimes, if you reply to different comments from the same person, you won't know which one you're replying to. Example: A: "The weather is really nice today." ＞B: "@A Indeed, the sun is so bright." ＞B: "@A It's a clear sky, just a bit too hot." ＞C: "@B Which city are you in? It's raining heavily here?" Both B's and C's comments appear on the same level under A's comment, making it unclear which of B's comments C is replying to.
