Change donate amount selection to Slider / Free Form instead of Dropdown

Currently the minimum amount for tips at the end of the month is 20 BAT. Since I had no chance to change it to something lower like 10, I decided to turn it off instead.

To accelerate this awesome feature which I still like, I think it would be better to grant users a bigger degree of freedom by changing this to something like a slider or free form element. That would make it possible to donate as much or as low as you want.

This could be even improved by making some kind of percentage from ad-earnings. Would be interesting to see if people are willing to donate, let’s say 25% of their ad earnings every month. I could imagine that some users are willing to do this, since it does not feel like “spending your own money”.

Let me now your thoughts and thanks for your awesome work!
