to have the checkbox "Send subscriptions notifications" on every page

I see - but currently only as administrator I can access it. And sadly I didn't figure out where to change this permission.

Would be great if the checkbox could be accessable by everyone who is logged in
and if it would look like the page when posting new comments (see attached snapshot).

Currently it's only there if posting a new comment, not when posting a new content or when editing a content or comment, even if it was posted by the same user.

This prevents some users to update content from time to time if there are only minor changes, because then everyone will receive a notification message and sooner or later the recipients would ignore notification messages even if there's an importent information inside.

I agree that for 95% or more of the drupal installations this makes sense.

But on my website I have only about 20 registrated people, using the private part of the website as an internal knowledge base. Most of the registrated users today use standard eMail as main information exchange channel. But it's sometimes difficult to keep the overview. Here the internal area of the drupal website comes into play. Currently the main interesting information and of course the files are uploaded.
Luckily now also a link to the uploaded file is sent out in the notification email (empty tokens). For new people in this group it's great to have such a knowledge base. And the people do rely on each other, so I don't have any problem concerning "reliability of Subscriptions".

For the ones who still prefer to use eMail and avoid using the drupal internal knowledge area, adding the feature request references in email headers would help much to accept an alternative usage of eMail and drupal site. Currently it's more used in parallel. That's not what I expected, but that's how it is, currently.

Avoiding sending out unnecessary subscription messages would enable the members who are not administrators to correct or update content with insignificant information without boring the others.
It would be perfect if a user could select "always send notifications" or "only send serious notifications". But I don't want to claim too much.

Because there is already that possibility to prevent sending out notifications (see attached snapshot from my previous comment) I hoped that it's easy to have this on every page. Just by changing a CSS file or adding a function call somewhere in the PHP code. Because the functionality is already there, it only has to be added on the other pages too. Or is this more difficult?
