In plasma you just add the Pager widget to your panel. In gnome you enable the “Workspace indicator” extension, which should be installed by default.

Both gnome and plasma have that feature. Plasma even lets you move the windows, I think in gnome you can only drag them from one workspace to another.

I use alacritty with a small script that calls tdrop to make it a drop-down terminal, and sets a few other window properties. For tabs I use tmux as it’s amazing and works everywhere.

It all works perfectly on X, but tdrop is pretty glitchy on Wayland with multiple monitors. Since I use the drop-down terminal a lot, that this was enough of a trigger to move from gnome to kde where I can still use X.
