Default [App Request] Pick up with button

Hi @all,

I'm searching for a "simple" App, but can't find one.
Maybe a XDA Dev can create one!?!

In the winter it is sometimes tricky to pick up a call with swipingfrom left to right.
It would be great if there would be an app where it is possible to configure a button (e.g. 2 times Vol+) to pick up a Call.

Would be great if someone with Dev-Skills could make such an App.

Thank you in advance.
