It doesn't show replies to the found comments.

not stable, also found that it slows video loading (refresh helps)

Keeps crashing all the time, so virtually useless for 50% of search attempts

It works as far as searching for comments goes but you cannot reply to any comments you found that way, nor jump to them in the comment section. So only about half as useful as it could be. But better than nothing, to be sure. The only reason it is even needed is because YTs comment function sucks ass.

It worked really well for about a year but then recently it stopped highlighting thins and didn't narrow down comments. Sometime it just says 0 comments. Whenever I type something in and press "enter" it just brings up the comment section that i can scroll down and see.

Always worked and sometimes it didn't work on certain videos but it was still great, but about a month ago it just stopped working (doesn't actually filter the keyword just highlights it but doesn't filter these comments just showing all the comments)
Edit: tried to uninstall and reinstall and have the latest version, don't know how to update permissions since it only shows what permissions.
Edit again: works again from the latest update but is working slowly

Doesn't load any comments a lot of the time.

Nice and useful tool! I have noticed a few issues tho: The shortcut is supposed to be CTRL+ALT+S but it was actually mapped to CTRL+Y for some reason. The cursor changes to move or resize the window, but neither actually work. Some of the results don't even have the keyword in them. I think it's because the word is in a comment reply but this just shows the last 5 replies of each comment. Also, personally I would have the window pop up in the bottom right corner instead of the center, but maybe I just have OCD. : P

there are bugs: the search returns also comments which do not include the search term!
e.g. searching this video https://www.youtube.com/watch?v=zZUOazRFLaA for "sortimo"
p.s. I think the error is at youtube because the web interface https://ytcomment.kmcat.uk/# returns the same results as your addon
p.s.2 https://hadzy.com/comments however works fine and i think is using the same api
edit: I used this add-on to search in the comments for just 2 youtube videos; it looks ok, but I would have colored the search terms in the result window;
I think you should complain to youtube about the error to have them fix their own bugs rather than rely on workarounds!
Is there another way we can communicate here except editing the review?
p.s.3 how about enabling Like/Dislike/Reply ?
can you implement this?
