I'm thinking that in parallel to the parseError signal, we can have a message(string) signal (for minibuffer messages) and a busy(bool) signal (for busy cursor), to which the bv would also attach at buffer creation.
In that way we can eliminate (some of) the buffer::getUser() [that will have problems with multiple bvs for one buffer for instance] and in general BufferView use inside Buffer/Exporter/Converter. Does this sound reasonable? Regards, Alfredo
