In reference to bug #160266, which was about there not being a "blank" option
(with the expectation that without such option, new data would just be appended
in a multi-session manner), I'd like to still very strongly urge you to
reconsider having n-c-b _automatically overwrite data on CD-RWs_ without any
warning (that I noticed, anyway). This kind of behaviour is hardly something
that a normal user can be expected to expect when he throws in a disc with room
to spare in order to burn some files onto it, and certainly is not appropriately
conservative, considering the destructive potential.

The best way to fix this would be to add multisession support (currently marked
WONTFIX for, IMAO, all the wrong reasons; see bug #120384), do that by default,
and support overwriting of CD-RWs via a _non-default_ checkbox.

Opening a new bug simply because #160266 was moved to documentation. Whilst I am
a bit hesitant in classifying this bug "critical" given the developers' stated
stance on these issues, I find that it, for the above reasons, qualifies for the
"causes loss of data" clause, which merits the classification. YMMV.
