This is a list of widgets from 2014. I like to see how the widgets fared over time. One I had looked at fairly recently. Some don’t apply to me, like the Opening Hours widget, which would be really good for a brick and mortar business website.

I’m going to try Biographia. It hasn’t been updated in 3 years but… it sounds interesting, if a bit complicated from the description in the review.
WP Biographia allows you to add a biography box to your website. It is, by no means, a simple plugin. The settings area has seven different pages. It allows you to define whether the bio is displayed before or after the content area on posts, pages, RSS feeds, archives, and your home page. It can also be displayed in widget areas.
