thank you very much for updating the CKE for WB. It looks good
and works fine.
Edit: Sorry. The last version (130429) has a bug, it is not possible to save any links (neither internal, external nor e-mail-links). They are displayed, but after clicking on "save" (the icon in the toolbar or the button under the editor field, no difference) the link disappears. (At least with the newst Firefox, Windows 7, WB 2.8.3 Rev. 1638)
This problem does not exist in the older version (130419).
I've noticed you added an option to chose a news item in the link dialogue. That's a great idea.
Maybe it would be helpful if there was also an option to chose a "Topics" item?
(I had already a look at the php and js files of the plugin but did not manage to understand the js part.)
