Sort "Currently Reading" on Home page by update recency

[MaggieFero]

Is your feature request related to a problem? Please describe.
The "Currently Reading" section on the Home page is sorted by the date the book was shelved, not by the most recent date it was updated. It also cuts off after 5 books. The cutoff seems useful, but combined with the shelving-time sort order it often means that I can't update any of the books I'm most actively reading directly from the Home feed.

Describe the solution you'd like
Rather than sorting this section by the time the book was shelved, I'd like to sort it by the time the user posted an update for that book (including shelving it, even if the initial shelving was not posted to the feed). This would put books that are being most actively read at the top of the list, and only users actively reading more than five books would still need to navigate to another page before updating.

Describe alternatives you've considered
I've also considered just expanding the number of books shown there to include everything, but this would likely incur a performance hit and users would still potentially need to scroll far through the list to get what they want.
