i think, its not the best way, if you use a module in the standard package when nobody from the DEV-Team work on it.
i understand, that wb in the vers 2.8.4 use a "new coding standard" or a "different kind of code writing", also new funcions etc
on the other side, marmot make's a top job with the ckeditor, he is also a very good supporter for (nearly) everything in the forum, but it looks not possible, that somebody take's this two parts and put it together

i work with marmot's CKE on the most of my WB's without problems, i use also a recoded WB-test-version of this CKE (maybe "recoded" is to hard to say), also without problems. i understand, that the DEV-Team say's, we have to change something in the code before we use it as a standard wb-module.
as example: wb2.8.4 use a new class to build (wb-)links to every modules sub-page (like news-pages, a special topic, a bakery item, a booking- or event-item etc) i used it also on a private module like (a small) members. you need only a file wblink.php in your module with a table- and a field name (and a little more), thats all. in my CKE-Test-Editor i can choice every bakery item, topics item etc in the wblink dialog
we build the same for the "marmot edition" (yes, me too), but its need a programmed database query and you need a query for every module, in the actual version the CKEditor has 3 different query's for news, topics and bakery
everybody knows, its not a good solution, if you make in one module a call to the next (additional) module
thats only one example
from my point of view its looks very easy: everybody works together and everything its fine - i have a dream...

maybe some little mistakes, some wrong words "in the last year" are a big problem today, but if nobody talk with the other part, nobody can fix the problems
I'm not a coder, i can read the code and sometime i understand. if not, i try different ways. it works for me, but its not enough for a complexe module like the CKE
P.S.:....sometimes i remember me, that nearly everybody says, the Internet Explorer is not a browser and today i dont understand, why the IE 11 is the "only one"
no question - the FCK is not the best, but i see no other solution in the moment
