Amazon has a history of shipping half baked features, and this is just another instance of that. Consider the Kindle Touch, which shipped without landscape reading and the ability to highlight across pages and no KF8 support. It took months to address these deficits, but they did address them, and continued with significant updates after that. They are going to do that with PW too.

Having announced these features would be delivered in November (they want to sell these things for Christmas season, remember), they had to deliver something to maintain credibility. And so here they have done that. They didn't say the features would be finished, they always have more on the feature roadmap than they can get to at any given time. There is nothing about the update that can't be addressed in a future update.

At a minimum, I would expect them to add Cloud & Device buttons to the bottom of a collection view so you can hide the Cloud items when you want to, and maybe rename Add to Collection to something like 'Add to or Remove from Collection'. I think too they need to have a switch on MYK to stop sync of collections so that they can behave exactly as they did before Cloud Collections (that is to say each device has its own set of Collections).

I think it would be worth exploring Collections that behave more like Items in the library. So you could Remove them from the device (without deleting them from Cloud or removing any items therein) and restore them from the Cloud on demand. Add a Delete From Cloud long tap option. Show them on MYK page and allow you to create, modify, delete, Send To there. (Of course, MYK itself could stand an overhaul...)

So I would advise some patience.
