We've had constituents ask us about this for about 6 years now - two asked me today. I thought for sure it was coming, but not seeing it directly mentioned here surprisingly.

Donors want a way to be able to log in and see their prior donation history. I know the service center is there for monthly donors, but this would be for any donors to see their past donation history. Seems everyone I talk to says all of the even small charities they deal with have this online option, and they find it odd we do not.
