I have never used Fluther on a tablet, and almost never looked at it on a mobile device.
On my desktop computer, right above the NEWER and OLDER links (which I don’t understand and stopped using because they often seem to link to questions with no posts I haven’t already seen), there is one labelled ”*Next Activity:” in bold, which seems to be the question which has the most recent unread answer, of the posts I’m “following” (usually as a result of having answered them), which I think is the same as the list in “Activity for Me” (which for me is mostly questions I’ve answered, since I have not asked questions very often).
I just tested my theory, and for me, yes clicking “Next Activity” takes me through the same sequence as if I used “Activity for You” and follwed the links there from top to bottom. But for me, not only does this take half as many clicks, but there is no 30-secord-or-so delay each time I load my 2500+ “Activity For Me”.
