"Jump to Top" shortcut ?

[Mrnofish]

Is your feature request related to a problem? Please describe.
If I get back to the app, there seems to be no way to get to the top and trigger a refresh. This can get inconvenient after scrolling through a lot of videos.

Describe the solution you'd like
Some kind of shortcut to jump to top. Solutions to a similar issue that I've seen in other apps include:

1. Tap'n'hold near the top bar.
2. Double tap on the top bar.
3. A button in the top bar.
