functionality like this threatens to turn youtube comments into a robust community forum.

Works great! The only minor issue is that it causes a "Permission needed" green dot in the Extension menu in every non-YouTube site (not sure if it's just something on my end)

After YouTube Comment Search another addon discontinued and stopped working, I found this addon. I love the interface and everything about it so much more. Fantastic job to the dev, this is a keeper!

Previously, I was using the other similar addon until I realised that its dev probably abandoned it without sharing the source code with others. Then, I found this. The most important is that it provides links to every comment so I can react or reply to it.

Its great and it works.
It would be better if I could disable automatic link detection in the options.

The constant notification dots on the addon icon are a little distracting.

An alternative to the standard application is very useful.
But the main point is functionality and convenient UI.

1. There is no way to view comments on community posts.
2. The window interface and pagination are not a very inconvenient solution.
In fact, there are three windows that can be conveniently placed together, otherwise they jump in a new place every time.
3. How to determine that a comment is hidden/deleted?

Essentially, you just need to display everything compactly, without empty areas. Arrange names, icons and other small things so that they do not eat up space that is not wide or high.
Immediately display all the text, and the built-in search in the browser will help solve basic functions, and you need to limit comments only in case of huge sizes (the total text is more than ...).
There should be a filter, but not intrusive, additional, hidden, secondary. Switch between modes: Two-level tree, two panels, table

commentviewer (dot) com sometimes seems more convenient
