Having looked at the bug reports and related messages, I have to ask. 
How does the GnuCash cash flow report compare to mainstream accounting 
software and practises? What Tim Barber and John Halton are asking for 
makes sense to me, but Carsten has implemented it differently. It seems 
critical to me that GnuCash is able to produce a cash flow report that 
conforms with generally accepted accounting practises. I don't see 
evidence of consensus or consultation with bookkeeping experts on this 
issue and that concerns me.
