@h-kataria can this also get your 👀 ?

[h-kataria]

@jntullo one minor comment do you want to move these new features above SUI and API features so all UI features are together, other than that looks good.

Checked commit jntullo@951ee2b with ruby 2.3.3, rubocop 0.52.0, haml-lint 0.20.0, and yamllint 1.10.0

Everything looks fine. 🏆

@jntullo @h-kataria will be added also some transformation mapping controller ?(I am not familiar with this feature) or no at all ? because role features are checked in UI automatically and name of role is inherited from controller name:

[controller]-[action_name]
