"ll" may not be the best choice of default alias - it's pretty common for people to already have it aliased to "ls -l" (or -la, or -lah, or whatever their preferred default flavor), especially for the type of power users this is targeted toward.
I realize this is a bit of a moot point since the user can always change the alias, but it's generally better UX if the default is something most people will use.
