For years it is possible to tilt widgets on the Plasma desktop. I think this was introduced in KDE4. I have never used it. I was wondering, does anyone?
Yeah, I do, Some notes and some pictures
What do you mean by tilting?
If you pres and hold a mouse over a desktop widget, then it enters the edit mode where you can resize it. And one of the options is also to rotate the plasmoid (the top icon in the column that appears on the right side of the widget, just hold it and drag it and it rotates the widget)
