A very unobtrusive and light-weight reading progress bar indicator showing the user how far scrolled through the current post or page they are. You can control placement and color of the progress bar, and you can choose whether it includes just the main content or also the comments.
The progress bar only displays once the user begins scrolling the page so it is as unobtrusive as possible. Once the user stops scrolling or scrolls down past the content the progress bar subtly mutes until it is needed again.
There is also a reading time commitment feature that you can separately enable. Control the placement (above or below title, or above content), style, and whether it displays on posts and/or pages. Uses 200wpm as the metric for average reading time.
You can also place the time commitment label anywhere you want via the [wtr-time] shortcode.

Looks very promising, but on my site, nothing was added.

Absolutely does not anything :(

An adjustable progress meter showing how much of the post/page the user has scrolled through, and a read time commitment label near the post titles.

“Post Length Indicator” displays a dual-coloured bar along side the browser’s scrollbar that shows readers what portion of the page contains the actual post content and what portion contains the comments. This is perfect for blogs that receive a lot of comments as it indicates to readers how long the article is and saves you from having readers turn away because your post appears too long.
The indicator will show on all posts that have comments, or that have comments enabled even if there are no comments yet. Text labels will display next to the indicator when a user hovers over it and clicking on each of the indicator sections will scroll the page to the top of the post content or the comments, depending which secion was clicked.
The colours of the indicator can be changed from the plugin settings page, as well as the post types for which it must appear.

<h3>Usage</h3>
