A thread was posted to the Comixology account yesterday, outlining a number of plans to fix things.
We understand that the current experience needs improvements and we are working hard to get those out the door as quickly as possible.
1./ We’ve been combing through your feedback, and continue to be grateful for all the comics lovers out there. We understand that the current experience needs improvements, and want you to know that we’re working hard to get those out the door as quickly as possible.

The app was broken in May. Getting non-comic results when searching for comics in your reading list is one of the most annoying issues. The thread says it is looking into the former issue and that you will soon be able to filter your library in the app.
There will be a new section that shows all the weekly comic releases in alphabetical order, as well as a new version of the web-reading experience that will bring back the double page spread.
You are correct if those sounds like features that should have been there. The digital comics application was merged with the ebook application by Amazon.
It's not clear why the merging of the two apps resulted in the loss of so many necessary features for reading comics, but it's deeply frustrating as Comixology is the only service available if you want to purchase digital comics piecemeal from a wide variety of publishers.
When these changes will come to the service is not clear. Changes will be in the coming weeks, while Comixology will let you know when other features are launched. You can read the whole thread here, and then come back here to discuss when they will fix Goodreads, an Amazon-owned service that has gotten worse over time.
