Thierry Dalon 2025-10-08: This is great but I am now disappointed that I have to pay for the Pro version to get more than 3 heading levels. It would be nice to have a separate documentation about the pricing so I don't have to click through to figure out it may be too expensive for me. I was also looking for a setting to select the heading level depth I wand to display. But didn't update to Pro now. Can't see such an option in the Free version.
Ka Shing Ngai 2025-09-07: very good!
Steve Dodd 2024-10-24: Brilliant - works really nicely with Kiwix archives of Wikipedia which seem not have a TOC by default.
Will Dong 2024-10-23: awesome!
陈乾 2024-10-05: Fantastic plugin. Immediately fall in love with it. Feature request: Hope there are per-website settings. I want it to be always on on all websites except a few.

Lợi Trần 2024-02-27: Love it, exactly what I found for long long time. It saved me tons of time navigating the content. The design is clean and easy to use too.
UltimoPenguin7 2024-02-23: Likely in search of SEO optimization, websites seem to be longer and longer these days, narrow widths, etc. This extension helps me filter through the noise and jump to the couple sentences I may be looking for. Thank you! 🙏
Edmundo Elizondo 2024-01-08: It works on some sites, on others it does not. It would be nice if it gave you the option of why and/or where it failed instead of just showing "Cannot locate article/headings".
Parker Conley 2023-12-09: Brilliant.

Hidenori Fujii 2022-03-11: Best outline extension! So much easier to read articles! But after recent update (v0.6.0), It looks like doesn't work shortcuts for Jump to next / previous heading... I heavily use this shortcuts so if you fix it, that would be great!

G I 2022-01-03: I don't know how I used the internet without it - it's a headache saver and very useful to be able to see what's on a page, get summaries, and navigate.

Alex Lee 2021-02-27: 好用，但是有时候会遇到bug，比如我拖动这个toc的时候，当我鼠标已经释放左键，它还会跟着我鼠标继续移动，即使关闭插件，然后再次启动插件，问题依旧。除非重新刷新加载网页。
