I am also a former Jerboa user and although I kinda liked it - the sole reason that I moved away from it was the lack of a proper search feature (It is already well-known that the Search bar in Jerboa is basically only for communities; Jerboa can’t search for posts, comments or users.
I have lately been using Eternity - and the main reason is that Eternity is a fork of Infinity for Reddit, and Infinity was a complete app by its own merit - so although Eternity is not updated frequently, it is very unlikely that I will miss any essential feature in Eternity for Lemmy.
