Every window manager there is with no default choice automatically listed when you choose a particular install with a sample picture and description for each.
Some say this is impossible. If Microsoft can do it then Linux should be able to do this.
And then an option to choose Dual-boot from the get-go. Click the checkbox and FC does the rest. Later when it's done it asks you to put in the other O/S CD or DVD and off you go.
Don't say this is impossible because you can do a single o/s install with Compaq SmartStart or Dell OpenManage and everyone can do this manually to date. It's 2005, surely they, that code things, are smart enough to make this a reality.
Also, this would be a HUGE plus if there was a notice that says: "Even if you uncheck this item it will be installed anyway because we've made it part of something else you clicked and you have no say if you don't want it".
And then the rest y'all can add to the list of things ya want....
