suggesting a markup ("track changes") toggle button for "markup" deletions with "strikethrough" and insertions with "underline", and "remove all tracked changes" button

[Wikinaut]

I suggest to have a new option "markup" (track changes) and a further button, "remove all markups"

If markup equals true then

• Insertions should be marked by underlines, when markup==true.
  (As a remark only: insertions are already marked by an author's background colour. The colours can be removed.)
• deletions should be marked by "striketrough" attribute instead of actually deleting such characters or lines.

I meant something like shown in the left part of this figure http://cloud.addictivetips.com/wp-content/uploads/2010/03/review1.jpg

Sounds like a huge pit of bugs. Microsoft has attempted to do this for over a decade, and even they haven't managed to make the interaction patterns make sense.

This was suggested as an option for authors:

When you press the delete button:
Characters are not deleted but marked with "strikethrough" (CSS "text-decoration: line-through") attribute, so that readers can see what is "marked as deleted"

An additional button is suggested which actually deletes the so-marked characters.

When you add (type) characters:
these are already added with the authors' background colour. I suggest that the added characters could also be underlined.

The additional button would also remove the so-marked underlined characters.

I pointed Wikinaut in the right direction to accomplish this. I doubt it is something we will see in core but it might be useful for some weird scenarios

As that's a plugin request, in fact, either re-label it or close it. :)

@JohnMcLear can you guide me what direction you provided to @Wikinaut so I can achieve it.
