If you have both hands at your keyboard, that's 100% true. However, it really works well with workflows which rely on mouse, stylus, touch, or controller input.
Especially when used for "creative" or "artistic" tasks (e.g. painting, video editing, 3D modelling, etc.) pie menus can really have a benefit because you have your hand at the stylus or at the mouse most of the time anyways.
Kando looks incredible - congrats! And I can see how it works well for the use cases you described. Maybe it would be possible to add keyboard support? One could use left and right arrow keys to highlight an item and the up arrow key to select it.
Radial menus never worked for me with a mouse pointer, even though I like(d) the idea in theory. Itβs somehow easier to reliably hit traditional rectangular menu items arranged linearly, then some wedge in an angle.
