I wanted to created a custom folding region (like it's described here), however "Surround with" is inactive for *.feature files. It's enabled for *.rb (but still no custom folding option in the menu). For *.rb files I successfully use #region #endregion, but what about feature files? Any options to have the same #regions?
At the moment it's not supported in RubyMine so others who'd like to see this option implemented might refer to the request you've submitted: https://youtrack.jetbrains.com/issue/RUBY-24080
