I gave it a fair shot for about a year, using vanilla GNOME with no extensions. While I eventually became somewhat proficient, it’s just not good.
Switching between a few workspaces looks cool, but once you have 10+ programs open, it becomes an unmanageable hell that requires memorizing which workspace each application is in and which hotkey you have each application set to.
How is this better than simply having icons on the taskbar? By the way, the taskbar still exists in GNOME! It’s just empty and seems to take up space at the top for no apparent reason other than displaying the time.
Did I do something wrong? Is it meant for you to only ever have a couple applications open?
I’d love to hear from people that use it and thrive in it.
GNOME does have a launcher, which works just like the launcher on Mac and Android. You can even select whether to see all your apps or only the most-used ones. I do agree that a taskbar/dock with intelligent auto-hide is a must, though (at least for my usability). That’s also not to say that some folks would rather have a Windows style launcher, and there are several DEs that provide that.
It’s not really the same design philosophy as iOS and Android since those actually have the equivalent of desktop icons, which function like a taskbar app launcher. So even they have a way of launching apps without a secondary menu.
