I don't see anything in the "User Control Panel" for this....

I find it very frustrating that the board marks EVERYTHING as "read" every time I sign out--this happens on every platform I've tried (multiple Windows version, iOS). It's especially frustrating if I get distracted while reading a thread and come back to find that I've been logged out (that's annoying, too, BTW--though, perhaps necessary for account security).

So, is there a means to avoid having posts marked "read" just because I visit the site (and then log out)? If so, I can't find the setting. If not, would you please consider adding it?
