hello
I think a good change for newer users is to make it to where the user interface is more user-friendly. I don't mean the whole app I just mean certain things. For example, one thing would be, is to make the options panels easier to stick. I didn't know that you had to drag the box to one side of the screen to get it to stick to the app. It took me the whole day to figure this out, otherwise, when you move the InDesign app to another screen those panels get left behind. So either have a little help box when moving the tabs called "sticking problem?" and have a small explanation or have the light blue sticking indicator be triggered inches before you reach the edge of the screen and obviously, you'll have to test it out though.

Put the "paragraph style" tab default on the paragraph tab. It's not there when I installed it, so I had to highlight something and in the properties and then I had to click the down arrow and click manage styles and poof there it was.

Another fix is to keep the options bar at the top when under the essential workspace. I would watch tutorials where they had this at the top and would this couldn't figure out how to make it work. An hour later I found a video that told me how to fix it. I'm new to this app but it would make sense that the essential workspace having it and the classic essentials would not but they are a switch. just add the option to the essential workspace that would be my fix. I'm sure there are more improvements but I haven't run into them yet
finally put on all your app, an ok box when either user first installs an or get an updated, stating that there's help for the user. And it would say instead of going to google or youtube that there are adobe cloud tutorials ready to go just for the user. :D. I didn't know this until I called customer support to help me with an issue.
