You're right about the fading — if you keep writing in one long block, lines stay. I write in short paragraphs myself, so I hadn't noticed. I'll think about how to handle this better.
On losing text: lines don't fade the moment you hit return. They wait until you start typing again. I found that fading on return alone left the screen empty at exactly the moment I needed to think.
The lag on Firefox/Ubuntu is something I'd like to look into — I haven't tested on that environment. The autocorrect issue is likely a browser limitation, but I'll see if there's a workaround.
