This plugin fixes the widget areas on WordPress widgets page on the admin backend so they always remain in view when scrolling up/down.
It will greatly reduce the time and effort in having to hold widgets and drag a long distance up and down.
Set to work from 481px and above i.e., only when the widget areas appear on the right side, in a column.
If you do not wish to use the plugin and want to temporarily achieve the same sticky widgets, bring up your browser’s dev tools and add this CSS to the widgets page:
<pre><code>@media only screen and (min-width: 481px) {

 .widget-liquid-right {
 position: -webkit-sticky;
 position: sticky;
 top: 42px;
 }

}
</code></pre>

Admin Sticky Widget Areas

I love the idea of this plugin, but it feels like it needs a bit of polish. While position: sticky; is enticing, the scrolling behavior is not great when one or more widgets are expanded so that the widget(s) you are editing are taller than one screen. In that case, you can't scroll to see the active widget areas until you've scrolled to the bottom of the page. Using some kind of JS behavior more similar to how the default core "Edit Post" page sidebar works would make this a no-brainer 5-star plugin, and I look forward to updating my rating!

Fabulous idea. Needs polish to be useful.

A simple plugin bat it solves a problem.

A simple plugin to make the widget areas on the right side of /wp-admin/widgets.php sticky.
