Just a heads-up: the documentation still refers to version 2.2, but the current version of the addon is 2.7
Make Instance
Creates instances with the initial position of the geometries.
Settings
Reset Position – Resets the positions of instances. I.e. everything is the same as what a split instance + mesh island does.
Custom id – sets a custom identifier for creating groups that will be considered a single mesh. Thus, the origin point will be calculated based on the ID of the group.
