Yes, definitely. Also you might be interested in https://github.com/nakajima/elementor although I haven't used it in a long time so I don't know how up to date it is. As far as your other question goes about how to use presenters, you probably don't want them emitting HTML. Instead you want the presenter to provide a simpler interface to some commonly accessed data that you don't think belongs on the model. An example might be class UserPresenter def initialize(user) @user = user end def full_name @user.first_name + ' ' + @user.last_name end end Ignoring whether this is an appropriate case for using a presenter, you can see what I'm accomplishing here. And hopefully you can imagine it being more useful if there are multiple models involved. A presenter is basically the facade pattern used specifically for presentation logic.
