FWIW link works fine for me (looking at other responses here).
Plasma’s global Edit Mode toolbar now has an “Add Panel” button that lets you add panels. With this located there, the desktop context menu has now lost its “Add Widgets” and “Add Panels” menu items since the functionality is fully available in the global Edit Mode. This makes the menu smaller and less overwhelming by default. Of course, if you want those menu items back, you can just re-add them. 🙂
I know it's not a competition, but that right there encapsulates what I see as the philosophy difference between KDE and other teams. I love Plasma as a user, but this sort of thing is why I arrived here from there in the first place. Am I going to put those menu items back? Nope. But I like that the possibility I might want to matters to the team.
