First of all; please look at this page I wrote for this specific subject;

Bookmarks seems to be a core thing that I agree should not become a 
plugin. Adding the public APIs in KoText and the widgets etc in the 
shapes/text plugin seems to be the way to go.

IIRC this widget requires;
1) access to the current (text) selection
2) access to the document to alter the selection-text.
3) a way to show itself in the GUI.

The first is a bit of a disappointment in that I expected the selection to 
be stored in a QTextCursor in the active KoCanvasResourceProvider. Alas, 
a QTextCursor can't be stored in a QVariant.   I guess we need to add 
several fields or a custom made struct for this purpose instead.
For 2 the same issue goes; we need to store the current shape and use a 
dynamic_cast to fetch the KoShapeData from the user object which will 
then give the QTextDocument we change.

For 3, yeah, I guess my explanation in the docs wasn't clear enough. Sorry 
for that :)
If you run KWord and press the right mouse button while the text tool is 
active you'll see the 'Autocorrect' menu option.   This will execute the 
code in /koffice/plugins/autocorrection/Autocorrection::checkSection()
See the api docs for KoTextEditingFactory::showInMenu()

Similar to the previous one.

Same thing.

This one should use the Docker plugin structure, I think.

Let me know if there are any problems left!
