Fedora 18
=========
- Add encryption option to text mode partitioning.
- Add simple keyboard layout selection to welcome language screen.
- Can the entry next to "Closest Mirror" be filled in with something to make it look less weird?
- Fix redraw issues.
- Make "Add custom repo..." dialog useful.
- Media install selectors take up all horizontal space on source spoke.
- Wall of anaconda needs to be taken into account.
- Why does the first hub jump left a little bit the first time you use the keyboard to navigate?
  Software selection also does this.
- In custom storage, it'd be nice to be able to say something like "Use this
  previous installation as the starting storage configuration for the system
  I'm installing now"
- In custom storage, it'd be really nice to be able to drag entries from old
  roots into the "New Fedora" root as a way of saying "Use this device with
  the same mountpoint in the new system."
- We're probably going to need to update the auto-generated names of container
  devices any time the user updates the hostname.

Beyond
======
- "Choose Disks" dialog before hub #1.
- Add device names to tooltips for DiskOverviews, etc.?
- Code quality:
    - Docstrings and comments are lacking.
    - Split out especially large spokes (storage.py, custom.py) into logically separate
      files.
- Device filtering.
- "Hub" shouldn't be in the page title for any text mode hub.
- Progress reporting for metadata downloading could be handy.
- Spokes should have some way to tell if other spokes are ready (see _software_is_ready
  in storage.py).
- Tracking and expressing dependencies on threads is tedious:
    - Create constants for thread names.
    - Add decorators to express the dependency and wait until it's met?
- Write out in-progress install to kickstart file, detect it on restart
