Do not use this feature that much but I totally get what you want. I am just not sure that it will give a better overview since some things will be harder to find when you need to go through all the levels.
Content -> Pages will be relatively straight forward, but I think that some will be really “deep” in levels, but I see that it will make sense since it will be the same “route” as in the menu.
I am with you that the current one might not be the best, but I am not sure that having so many levels will help in how fast you can find the info you need
Very very open to suggestions with this one, I imagine this improvement will be quite some time away so lots of time for partners to add their ideas for improvement.
I completely agree that this needs to be refined. I think It should reflect and layout just like the actual menu. I am also finding that some options don’t work or the don’t work like I think they should. For example it looks like you can set the default for custom modules so you don’t have to do it module by module. I find that this doesn’t work when I did it a few days ago.
