Here is an example of one I received a while back, but haven't included in the daily email because I was afraid it was a bit too niche.
"I work in sports photography.
A problem I face is that I spend a lot of time grouping and sorting players in uniform.
The software I want would read the jersey numbers and tag the image with the players shown in the picture. Then it would allow manual tagging for those with jersey numbers not visible.
I would pay for this software."
