## Description
In order to improve the first load of the applications, now we're only
rendering the widget components that are [above the
fold](https://en.wikipedia.org/wiki/Above_the_fold#In_web_design) right
away and rendering the other widget components whenever the browser is
idle. This decreases the amount of time it takes before the first paint
on the screen.
This is getting shipped behind a feature flag!
