Sentence Segmenter

This extension will make your text easily readable by separating sentences based on periods.Github:

It puts each sentence of a webpage on a new line.

If you need to reread, it can be faster to find the beginning of sentences

Sentence structure can also become clearer.

If you’re skimming, you can abandon a sentence, and quickly find another sentence.

You can activate the segmentation by clicking on the icon, or right-clicking (context menu).

You can segment the entire page, or a smaller section.

---

For highlighting and segmenting smaller sections, you can turn on an element highlighter that appears as you hover the mouse.

It’s similar to the the Chrome element inspector, and the EasyReader extension that pops out content into a more presentable view.

Spacing between sentences is similar to the Microsoft Word setting:
Microsoft Word -> Home -> Paragraph -> Indents and Spacing -> Spacing ->
Line spacing single
Before After 6 pt

In addition to spacing, you can place line separators between sentences to further distinguish between sentences.

Segmenting a page is like creating a snapshot.
Certain elements can't be clicked on and expanded anymore, like comment threads.
Expand first if necessary, and then segment.

You can refresh the page to turn off the segmentation effect.
Going further, there's a “Turn Off” check box to turn off the extension.
