Layer Distributing option lets you decide what happens when layers cannot be distributed evening using full pixels.
New Groups gives you the option to select layers within any new group you create without having to hold ⌘ or open the group first.

Vector Import attempts to interpret the path data inside PDF and EPS files you import and make it editable, rather than importing them as flat images.
Artboard Exports gives you choose how Artboards are ordered when you export them as a PDF.
Editing Shapes lets you choose whether not to close the path by clicking on the first, or last, end point when editing an open path.
Offset Duplicated Layers will offset any layer duplicate by 10px from the original.
