The different custom shapes now default to trees, leaves and animals. Maybe next time you can replace commonly used symbols and graphics with sounds and feelings. That, or you could simply just leave the stock set of shapes that we've all grown used to over the last 20 years alone?
While not condoning the OP's bad manners, I do feel his/her pain. The defualt shape list we are presented with nowadays (trees, animals, boats and flowers) makes no sense to me. The saving grace is that ability to rearrange by dragging individual shapes and folders is common to all functions that can have a lot of presets, so the argument might be that we are given a starting point, and encouraged to organise things to suit our personal workflows.
