I consider the lack of segmented patch chords a nifty feature that keeps MAX users away.
I started with PD and am pretty well comfortable in just laying out my patches in an efficient manner.
As previously stated, there's always [t a] if you ever need a segment.
However, if that is one of the glaring issues that people really want well ... welcome to open source, unlike MAX you can grab the pd source and jump into some tcl/tk!
.. better yet, how bout someone port Audicle from Chuck to PD: http://www.youtube.com/watch?v=hFAh-pgxGyc
Then you get all of the fancy stuff! Buttons and flying graphics.
Sarcasm aside: I use pd because its small and fast, so I deal with the "sparse" interface options.
