Thank you very much!
This looks quite good already. I only have two thoughts:

1. I think this deserves a release note
2. I'm unsure about the page view at the moment. I think I would have put "Cancel" at to the far left, but maybe this is a question for @nikolahoff. Do you like it the way it is at the moment?

I think you are right, but let's wait for @nikolahoff opinion :)

I think there are too many buttons and styles on the same page. But maybe we can leave it for now and wait until I have done the overall review because this would effect other pages as well. @JoeyStk @lunars97

[JoeyStk]

@nikolahoff Thanks! Yes, sounds reasonable. Until then, do you have a preference whether or not it should be before or after the "Preview" button? :)

[nikolahoff]

@JoeyStk I would put it before the preview.

@osmers
I have some questions.

I understood the scope of issue as following: a cancel button should be added to all the forms onto which region users can land if the corresponding object has a tree or list. Therefore meida library, imprint and machine translations are exempt of this change, as they do not have any tree/list, and region, language, users (in Network Management), role, offer template and location category too as they are only available for staff users.

If this interpretation is correct, the button is missing for the form of contact, external calendar and user. I guess the first two are not listed in the issue because they didn't exist at the time of issue open.

And the cancel button will not be shown if the opened object is archived or the user does not have change permission (observer role), but they probably want to go back to the list by the button (once it's introduced) after checking an archived something.

@MizukiTemma @osmers should I add cancel button for form of contact, external calendar and user? 🤔
