Gnome's UI peaked at 2.32. Find out how the users operate and implement so users can work efficiently. Don't make changes just to make your mark or to make users work on the desktop like they see on a cell phone. That is so basic.
I don't know if you are DE shopping, but I've been very happy for the past few years with the MATE Desktop Environment, which "...is the continuation of GNOME 2. It provides an intuitive and attractive desktop environment using traditional metaphors for Linux and other Unix-like operating systems."
Among a great number of things I really like, I will mention that Caja, the MATE version of GNOME 2's Nautilus file manager, can still be switched to spatial mode.
I have no idea why Gnome keeps on insisting on breaking expectations. From the shell as a whole to the widgets and even the window titlebars they seem to insist on being different for the sake of being different.
Because their choices are better, at least for some of us. Users who prefer the traditional desktop paradigm have a wealth of alternative DEs to choose from.
I suppose my brutally minimalist Sway config with barely there titlebars and a skinny little status bar and not an icon, button, or widget in sight doesn't give me great standing to call for a respect of conventions.
I suppose I should say I found Gnomes luridly chunky decorations and widgets to be personally offensive.
Gnome is always getting better (if you want to do things the Gnome way). Why should a DE show any elements begging to be clicked on my desktop while I am working (window list, etc)? I am only interested in what's in my IDE, terminal, and browser. Present Gnome comes closest to my ideal of fading into the background and letting me focus on my tasks.
(I needn't say more.)
