For 1 dollar it would not be worth creating the feature.
Thats a pretty bold statement if you know neither the cost of creation nur the potential sales.
A simple name change for the cost of 6 months supporter?
If you offer it for 1 dollar you would make hundreds or even thousands of dollars every season (in addition to hundreds and thousands of happy users).
I srsly doubt any1 would pay 20 for such a small feature, recession and so on, nahmeen?
