Open the README file for utilities, from the utilities tab.
I am officially requesting that time-of-release the MacNewbPack includes documentation for the utilities it ships with, including a .txt or .html with links to the development site of these projects. I've just spent about an hour trying to find the documentation for Dwarf Family. Do you have any idea how many hits "Dwarf+Family+utility" gets on a website called Dwarf Fortress? Fer'serious!
Edit: About half the utilities are already shipping with readme.txts and .pdfs, so I guess what I'm asking for is a duplicate copy be set up in a Help folder, and that links to the project documentation be added for the missing ones. At which point, you may as well add in a button on the Utilities tab for that folder.
Obviously adding or creating README files is the responsibility of the utility developer, or falls to the pack maintainer.
Adding a button to each item on the utilities list, to open an autodetected README file with the default app for that file type, would help expose documentation to users. I've been planning to implement this eventually, but a user request means this deserves a spot on the issue tracker.
