Only issue I'm seeing now is when looking at someone else's comments or "Your content", it shows both public content and PM content. I think @Okku mentioned this a while back.
Dark or Light style?
I do see that when highlighting text, only in the reply-box, does it have the dark tint like @upNdown is talking about.
This will be fixed in the next update which I expect is coming soon. It does respect privacy so please don't be alarmed. DMs will only show in the results when you search "everything" or "direct messages" after the next update.
