Custom donation amount

Hello, i think it will be good if you guys add custom donate amount.
In the current version of salad, if i want to donate 10$, i have to do it 100 times, because The price of the maximum donation is $ 0.10 only :frowning:

I think its a good suggestion, i hopy you add it in the next update! :smiling_face_with_three_hearts:
