The settings allows you to turn particular features on and off in the tool. Currently there are only two settings that can be enabled in the tool. This is:

Add Orchard File: This will add the document file that contains the process information to any email that you send. It will appear as an attachment alongside the tool.

Show Hints: Having this setting on will show hints in the top right window of the display to assist you with becoming familiar with the tool. Once you are familiar with how the tool works, you may want to switch this feature off.
