This one is probably not going to happen, but it would make life easier for us writers. Hear me out:

What if you could change your status from Reading to Writing?

That way when people wonder where you are they can say "Oh they're busy writing, so they will probably respond later".

I mean you never know whether someone is just reading on here or actually writing a chapter! I'll be busy writing then my Notifications flare up and when I eventually respond some (very little) people will be like "WHY DIDN'T YOU ANSWER ME SOONER?!"

Then I'll start feeling irritated because I was writing and I never stop in the middle!
