Sure, but the remainding 99% will set a read-flag.
We have some ideas of how to merge loads of these read-flags into one
transaction, but I'm not sure it will be useful. I'm just very lazy and
don't want to implement something I don't need. :-)

Nah, it has to be set on a user level, not on a computer level.

Very helpful, thanks!
