Just some gripes I had to write down somewhere.
My monitor (a 'classic' 21" Sun GDM 5010 [aka the radiation king]) has often not been properly detected, but has always worked well, pretty easily on every branch of the redhat fork that I have used since RedHat Linux 5 in the late 90s. I must say that I'm extremely disappointed that there's no obvious way to manually select a monitor for your x windows configuration file. 'Automagic' configuration through probes sure is neato when it works, but not having an alternative other than combing online for examples for xorg files to copy and tinker with seems like a huge step backwards for users in my boat.
I can understand the coolness factor of not needing max/min/rest buttons in your GUI, but why would you make that the default when there's not a fix that doesn't require intimate knowledge of the configuration tools or a web search? Didn't you even do enough testing to realize that on a vanilla install, if you go to help->about firefox there's no way to close the window without right clicking on the *2 shades of light grey darker than the window background* toolbar and selecting close? Now that's usability baby!
If you want to make a mickey mouse interface for newbies... that's totally great. It really is. I completely support making the software more accessible. Just don't take away my power tools. There are distros for dummies and that's not what Fedora has classically been about. It's great that you're trying to make things smart, but smart isn't nearly as reliable, and taking away the reliable... that's just... well, dumb.
Oh yeah... why on earth would you have a menu where you could log into your chat session without any method of accessing any buddy lists or other chat controls from that same menu? Truly bizarre.
