Having a real time call log would be great, even if delayed by say 10 minutes or an hour.  Or still useful if delayed 24h, but to a much lesser extend.

A business application would be call logging for a motel or homestay or...  It would also mean users can inform WxC of a possible error earlier rather than only a month later after receiving an invoice.  Having the cost there as well would be nice, but even better if it is optional so you can hide it if need be.

Another application would be claiming expenses from your employer.  My wife travels a lot for her work and at the moment she simply claims an expense for a mobile phone prepay card, but it would be so much better to have an itemised statement especially with VFX low rates.  I have not yet received my first VFX statement but assume it would be itemised, but again one have to wait a month before receiving it and then another month before the employer actually pays for the expenses (with other stuff my wife gets paid for the expenses before the credit card bill is due, nice).
