I find it helpful to set a different wallpaper for every space. In fact, that approach has been so useful that I’ve mostly stopped wishing to rename the spaces – I can glance at the colors so much faster than I could ever read a written title anyway.
Yeah I do this too, I can't imagine not having different wallpapers. But when I'm pinning apps to desktops via the Dock it'd be nice to have the names then.
