Order of no particular importance:

*** Make the daemon aware on how long between updates ***
Requires writing to a database for config stuff
 - Probably should move the job number stuff there too
New method GetHoursSinceLastUpdate
Use this in the update icon

*** Add new callback for status ***
TimeRemaining()

*** Prepare download to refresh system ***
Either use a flag or a new method. I'm not sure which yet.

*** Add a way to import GPG keys ***
In fedora, if you add a signed repo you have to agree to the GPG key.

*** Split up PolicyKit install into different types ***
Have different permissions for signed and unsigned repos.

*** Handle rollbacks for select backends ***
To do rollbacks sanely in PK we need a few things:
 * allow transaction data to be changed in _db

*** Use resolve for pkcon operations ***
'pkcon install zsh' should work as well as 'pkcon install "zsh;1.0;i386;repo"'

*** Unit tests ***
PkSpawn is a complex and untested bit of code.

*** PkSpawn enum return value ***
pk_test_finished_cb (PkSpawn *spawn, gint exitcode, gpointer data)
- exitcode is undefined - make an enum
	PK_SPAWN_EXIT_SUCCESS
	PK_SPAWN_EXIT_FAILED
	PK_SPAWN_EXIT_KILLED

*** backend docbook ***
Explain SIGQUIT and SIGKILL in the docs
