I think that virtual desktops are criminally underused by users, especially those introduced to newer (KDE 5) versions of Plasma. I've seen a few default installations of "n00b" distros like Kubuntu and there's only one desktop enabled by default, so many people don't even know of the feature.
In comparison and as far as I remember, in KDE 3 days, you basically started with a 2x2 grid of virtual desktops, so you practically couldn't be ignorant of the feature. [*]
A few more notes after watching the linked video:
- I don't know why he uses the Super key, it was always Alt on my machine. Though maybe the defaults changed in Plasma a number of releases ago and it's just me sticking to my good ol' config, so bear that in mind whenever I mention using Alt key below.
- I tend to use the no-border feature for some applications extensively to the point of remembering the proper key sequence, provided you're using en_* locale: Alt+F3, then 'm' for "More Actions", then 'n' for "No Border".
- If you're doing this a lot or tend to position specific applications in specific ways, sizes and/or parts of your desktop, you can predefine a set of rules for the window manager to handle and enforce them for you. Look at: System Settings -> Window Management -> Window Rules.
- I strongly suggest enabling virtual desktops, at least in a 2x2 layout and setting up the following shortcuts: Ctrl+Alt+arrow for moving left/right/up/down across them; Ctrl+Alt+Shift+arrow for ditto but dragging along the currently focused window. System Settings -> Shortcuts -> KWin, look for "Switch one desktop ${direction}" and "Window One Desktop ${direction}".
- Use yakuake, but change the shortcut from the stupid F10 (or was it F12?) to Ctrl+Shift+` (left apostrophe, the one with ~ above it). That way you can still switch it on and off with one hand and you don't block out the ability to use either left apostrophe nor tilde for typing.
[*] Though I'm still salty that the "modern" KDE removed the feature of having a different wallpaper on each desktop. But at least they've hidden the cashew.
