&gt; I don&#x27;t see how this is any worse than separate buttons - you&#x27;d still have the same physically clickable area then (the bottom bit) but you&#x27;d have less space to drag the cursor around.<p>Sure, but with physical buttons I know if I&#x27;m on a physical button. With this thing, sometimes clicking just doesn&#x27;t work because I&#x27;m too far up and I have to move my finger down to where it&#x27;s magically clickable again.<p>&gt; Seriously, this is just what&#x27;s available out of the box with OS X<p>I dunno, I don&#x27;t use any of that stuff. I do 90% of my work from the Terminal. I drag windows, scroll, and select text (ugh) and that&#x27;s about it. For my use case, this thing is no improvement over buttons and often a detriment.
