Not so much an idea, but an observation. I noticed that there is an update to how sections are added to a page in the page editor. It used to be that you would click to add something to your page, and then there would be tabs on the top of the left sidebar, where you can choose between modules and sections.
Now you have to click the plus icon on the left add something, but you only have access to modules on the sidebar, and you have to go back to the editor box and click a button that says "Add Section" in the middle of the page, which will bring up a modal with two columns of page sections to choose from.
I think the modal box with page sections looks nice, but I'm not sure this is an improvement from a UI perspective, because you are sending someone to the sidebar, just to send them back to the middle of the page, and now modules and sections are in 2 completely different sections of the editor.
Also, when everything was on the left sidebar, the sections I built were in alphabetical order, and the user could see the description I wrote for every section. Now, I cannot find any recognizable pattern as to what order the sections are in or why they are in that order, and I can no longer see the descriptions I have written for these sections.
I personally feel like having the sections in an easy to recognize order (like alphabetical) as well as having the descriptions available made for a better user experience.
