Hi
Good idea! Let's make that #4: Fedora Guide to Power-User Tweaks.
Are
you volunteering to create and edit it? (I wasn't volunteering to head
a project to create defaults, so you can say no to this as well.)
I am willing to edit it but authoring is better done by people who love
fiddling with these things. I rarely use such tools myself. If anyone
else is interested see

regards
Rahul
