• Extension that does something like this:

  def build(*)
    if settings.memcached?
      use Rack::Cache, :backend => :memcached
      use Rack::Session::Memcached
      # ...
    end
    super
  end
  

• sinatra-smart-cache: update cache header only if arguments are more restrictive than curent value, set caching headers that way for most helper methods (i.e. send_file)

• Some verbose logging extension: Log what filters, routes, error handlers, templates, and so on is used.

• Form helpers, with forms as first class objects that accepts hashes or something, so the form meta data can also be used to expose a JSON API or similar, possibly defining routes (like "Sinatra's Hat"), strictly using the ActiveModel API.

• Extend sinatra-content-for to support Liquid, Radius, Markaby, Nokogiri and Builder. At least the first two probably involve patching Tilt.

• Rewrite of sinatra-compass?

• Helpers for HTML escaping and such.
