Would be awesome if nitter supported infinite scroll (upwards) for earlier replies in a thread. Currently it requires clicking on "earlier replies", which results in losing the context of what tweet you started from and therefore not being able to scroll back down to it without having to find it out of all of the replies.

If infinite scroll was supported (the way twitter currently does so) this problem would be solved and the context of which tweet I came to the thread from would not be lost,
