Sounds bad
What is an "Activity View"? I'm thinking its not something I want. I've never used multiple workspaces, so hopefully all that stuff for them will just vanish 100% from the screen.
I've been an Ubuntu user for many years. I spend much of my day sitting here, programming, testing, debugging. My screen is a 1920 x 1080 monitor rotated to portrait mode. I have two permanent xterm windows - one on the left where I run stuff, do email with Alpine, etc. The one on the right runs mouseless Gnu Emacs. There I do my editing, compiling, etc. That leaves a bit of space on the right where I have Mate's panel. It has icons for a few status indicators, common program launchers (e.g. Firefox), and my active programs.
I have an incredibly poor memory, so don't even try to remember key combos or mouse waves. I have no interest in the system scanning my stuff, so turn off the thing that nightly scans drives and builds an index. I start programs from menus or commands, not from some goofy "search" thing.
Tried KUbuntu for a while a few years back. Hated the "Peanut" thing I couldn't get rid of - never even understood what it was for. Couldn't understand their complicated settings filters, etc. Settled on Ubuntu Mate - comes with customizable menus which remind me what the weird names of needed-but-not-commonly-used programs are. So, will there be something usable for me, or am I doomed to continual frustration and annoyance?
