Hi,
Thank you for your comment and suggestion. I never thought of that option but I think it could make sense. I don't know if it is feasible, but for sure I will add it to my to-do list for this extension: https://rumoroso.bitbucket.io/headingsmap/todo.html

Thank you again for writing a comment and suggestion ;)

Hi Doug, thanks for sharing your feedback. I am always happy to know that the extension is useful and also to have this kind of feedback that gives additional ideas of features that it could include.

Regarding your suggestion, right now there is a visual clue that can help to identify the header. Maybe it is not the best way, but I think it could help. If you go to the settings dialog, you'll find one option with the label "Relate with viewport". When it is active, besides each item in the list of headers, at the right, you'll see a grey line that, when you scroll in the page, visually identify the headers (or sections) that are in the viewport area. When writing this comment I am thinking that maybe it is not the best name for the option. I also think that it can be far from your suggestion, but maybe it can help a bit.

Anyway, I just included your suggestion in the to-do list that I have: https://rumoroso.bitbucket.io/headingsmap/todo.html I have to say that some of them have been in the list for some months, so I cannot ensure when are going to be implemented, but at least it is a place to not forget them.

Again, thanks for your comment and your feedback

Hi, thank you very much for your comment and suggestion. I have to confess that the idea of a custom shortcut is in my to-do list, so I hope I will work on it soon https://rumoroso.bitbucket.io/headingsmap/todo.html ;)

Hi Nijaz, thanks for your comment. Knowing that the extension is useful always makes me happy ;)

Thank you very much for your comment, and specially for sharing the idea of that potential new feature (which by the way I like). I will include it in the "to-do" list. I think this can go in parallel with other that is also in the list, which is to somehow show reflect the position of the scroll in the page regarding the headers, with the headers in the extension.

Hi, thanks for your comment and rating.
Regarding to the sidebar, I totally agree with that idea. The extension, while XUL could be used for integrating it in the browser, was always a sidebar panel, so it was perfect because it didn´t interfere in the page and, additionally, could be open while browsing between pages.

That had to change with the new webextensions API. The advantage of this change is that the same development works for other browsers.

I have in mind to try to include it again as sidebar panel. Right now I am working in a change for giving additional feedback for SEO analysis. Once it is done, I will try with the panel ;)

Again, thanks for your comment. This kind of feedback keeps my motivation for trying to make it better ;)

Hi hmijail, thanks for your comment and feedback. I think it is very useful and made me see other point of view.
The weight that the extension has now is caused by an error that I made when including the spinner-gif that is shown when generating the trees (the HTML5 outline takes time and I thought it was good idea). I just realised of it because you mentioned it. The problem is that I didn't optimise it (maybe half of the size is because that gif). I will fix it in the next release.

Regarding to the often updates, to be honest, I didn't think that could generate some concerns, but it is good that you brought that idea to me. I have been adding lots of changes that mean some new features, also improvements in the performance and a couple of bugfixes. I usually release the changes as soon as I apply them, instead of waiting for having a bunch of them done. I would say that it is more like a continuos delivery than a scheduled releases. I think that, after this, creating a page with the release notes could be a good idea, so they can be accessible for anyone. Just to cover a bit my lack on creating those release notes, some of the changes I introduced this week are:
* New features (some of them):
- new panel for settings (it appears inside the panel)
- new dark theme
- option for including the aria-label content
- resizer for the panel
- option for placing the panel in the right side
- CSS overscroll-behavior property set to none for preventing the scroll of the page when the tree has scroll
- ...
* Performance:
- refactor in the code for improving the speed in which the trees are generated
- only the tree of the current tab is generated (before this, both trees were generated always)
- better DOM structure of the content
- ...

I also applied some minor changes that made the code more clean and structured and also some bugfixes. Ah, and I updated the code so the version for Chrome of the add-on shares the same code, helping me in the development process because there is no duplicated work.

So just for finishing this long comment, I can tell you that the add-on hasn't been hijacked and still keeps the initial intention that always had. Anyway, I guess that if that would be the case, the Mozilla review (step that is executed before any release) would block the release of the add-on.
Thanks
