I am liking the reliability option, but it would be great if "ordinal" omega and alpha were included in addition to the regular alpha and omega. For Likert type scales, these reliabilities can be largely attenuated when failing to account for the ordinal nature of the data. (adding confidence intervals would be great too)
I use the 'userfriendlyscience' R package to calculate my ordinal alpha and omegas (this package draws on the 'psych' package)
