The topic can be closed, I've pmed people and we'll see what happens.
I've obviously used it, I tested it a few times when I found it, but more or less completely forgotten about it since then, because it's not that useful really.
I just rediscovered it by accident again and thought I'd ask this time.
Not sure how long I've known about it, could be 6 months or it could be 1 year+ I have no idea. Think I found 1 or 2 other minor things that could be considered bugs, but they were either fixed or I wasn't sure if they happened after the rewrite or have just been there all the time so I didn't bother reporting them.
