Couldn't remember where else to put this, I have a legit complaint about the new reply box.
Copy-pasting something into a post makes it come up white, so it's hard to edit or see what you're doing without changing the text color. If you change it to black in order to know what you're doing, you have to then change everything back to white or else it's not visible when you send the post.
Why did the reply box change? Don't fix what isn't broken (unless it's fixing poorly balanced characters, in my case).
