Smooth corners and handle behavior

  • Hi there,

    I have a couple questions regarding point behavior:

    1. Why are there smooth corner (square) points? This only seems to yield outline errors in the UI or unusual handle generation upon opt-click-drag.

    2. Why does option-clicking or dragging on a segment sometimes also affect (and sometimes only affect) the adjacent segment?
