task: implement multiple edit sessions per document

Filed bug 74922 on the implementation details.

-> 0.9.1

move 9.2

-> mozilla 1.0

Bugs targeted at mozilla1.0 without the mozilla1.0 keyword moved to mozilla1.0.1 (you can query for this string to delete spam or retrieve the list of bugs I've moved)

don't move bugs that are in the 1.0 dependency tree. sorry.

-> mjudge

removing myself from the cc list

minusing to topembed- as per edt triage since editor is not in the radar for the current embedding customers.

since bug 74922 is fixed, is this fixed? What more specifically needs to be done here?

The purpose of this bug was twofold. First, the need to allow the user to have multiple editing sessions within the same composer parent window. The current implementation causes a new composer window to open, resulting in numerous open composer windows. The second part of this bug was to allow the user to have multiple sessions of the same document.

I would call this a feature enhancement of allowing the UI and focus to know about multiple editor windows. I don't think embedders need this right now. I will reassign this to syd.

Once bug 66305 is fixed and Composer removes dependency on "editorShell" (bug 158881, bug 121648), this should be a relatively easy task and will open a whole new world of capabilities for Composer! E.g.: editing frame docs (bug 14156), muliple editor windows ('tabbed' editor), better HTML source by using full PlaintextEditor bug 69329).

Changing focus of bug to multiple edit session per Composer window. While the second goal of multiple edit session per document (DOM tree) is useful as well, that is a more difficult and less important problem to address in the near term.
