Thanks @maurerle for reviving @arteagac's contribution! I tested this locally and it's working as expected.

However, I'd be in favor of wrapping lines per file instead of doing it for all files (as in this PR). That's why I'd suggest to change wrap_lines_action to be a regular action (i.e. non-checkable), such as trailingspaces_action, which only has effect for the current file.

By doing that, we'll also be able to remove this option in our Preferences:

which I think is of little value because you don't want to see all your files wrapped.

This is a display/visualization setting which has two states (wrap lines on or off) I don't think that something without a checkbox is sufficient here.
It does not change the actual lines like traliningspaces_action does.

Notepad++ has this feature implemented as it is currently in spyder (once for all views).
PyCharm and VSCode remember this setting per opened editor.
All three use checkboxes to indicate the current setting.

I actually like the behavior as it is best.

Wouldn't this be a nice addition to the 6.0 release too? 😊
