It would be fine for me, but it is laggy. Could you somehow use FF Autoscroll algorithm for smooth scrolling? It would be important for me. Thank you very much!

Luckily for my purposes the speed is about right, and the integration of the refresh step is perfect. As others have said, this app would be a 5-star if speed and actions could be controlled. Looking forward to those updates!

If I wanted to contribute how could I (financial donation of a few dollars from many users could be good for you)?

It would be much better if the speed of scrolling and an action for scroll-end event were adjustable.
