This update completely destroyed the notebook search functionality. I would say that it's the most disappointing change to the entire thing. I want to clip something and I want to quickly start typing the first letters of the notebook, and it has zero accuracy. Even if I type the exact name of the Notebook it claims that it doesn't exist. So then I manually scroll through all of my stacks and notebooks and there it is.
The previous version was perfect in terms of usability on this feature and it got completely destroyed for a power user like me.
As you can see from the attachment I type the word, "Recipe" and it shows nothing. Then in the second attachment I scroll down to show that it recognizes that the Recipe's notebook does in fact exist.
