I don't like the idea of a visible pie chart, but an invisible one that
provides scrolling as you drag outward & clicking in the middle would be
great. That's what I originally thought was implied on the wiki page.
Used in this manner it would also be completely intuitive.

I have to agree with you on all these issues. Also what people don't
understand is the physical screen size is less than half the size of the
online screenshots. 2x the dpi means 2x smaller screen than what you
see on your computer.

I can see limiting, but not removal. Removing on-screen clutter and
keeping everything big would be more effective, in my opinion.

why not just double-click to double-click? that seems far more intuitive
to me (or don't use it at all).
use the tap&hold for a right click. many programs almost require a
right-click. you also know you could right-click on those early macs by
pressing the option key & clicking. i think the right-click is too
important to ignore.

totally agree. that would be perfection and useful in almost all apps.
