+Miscellaneous ways to improve your Rails experience
+===================================================
+---
+date: "2014-05-08"
+---
+
+Recently, I've been working on [a Rails web application][leaguer],
+that's really the baby of a friend of mine.  Anyway, through its
+development, I've come up with a couple things that should make your
+interactions with Rails more pleasant.
+
+## Auto-(re)load classes from other directories than `app/`
+
+The development server automatically loads and reloads files from the
+`app/` directory, which is extremely nice.  However, most web
+applications are going to involve modules that aren't in that
+directory; and editing those files requires re-starting the server for
+the changes to take effect.
+
+Adding the following lines to your
+[`config/application.rb`][application.rb] will allow it to
+automatically load and reload files from the `lib/` directory.  You
+can of course change this to whichever directory/ies you like. 
+
+	module YourApp
+		class Application < Rails::Application
+			…
+			config.autoload_paths += ["#{Rails.root}/lib"]
+			config.watchable_dirs["#{Rails.root}/lib"] = [:rb]
+			…
+		end
+	end
+
+## Have `submit_tag` generate a button instead of an input
+
+In HTML, the `<input type="submit">` tag styles slightly differently
+than other inputs or buttons.  It is impossible to precisely controll
+the hight via CSS, which makes designing forms a pain.  This is
+particularly noticable if you use Bootstrap 3, and put it next to
+another button; the submit button will be slightly shorter
+vertically.
+
+The obvious fix here is to use `<button type="submit">` instead.  The
+following code will modify the default Rails form helpers to generate
+a button tag instead of an input tag.  Just stick the code in
+[`config/initializers/form_improvements.rb`][form_improvements.rb]; it
+will override `ActionView::Hlepers::FormTagHelper#submit_tag`.  It is
+mostly the standard definition of the function, except for the last
+line, which has changed.
+
+	# -*- ruby-indent-level: 2; indent-tabs-mode: nil -*-
+	module ActionView
+	  module Helpers
+	    module FormTagHelper
+	
+	      # This is modified from actionpack-4.0.2/lib/action_view/helpers/form_tag_helper.rb#submit_tag
+	      def submit_tag(value = "Save changes", options = {})
+	        options = options.stringify_keys
+	
+	        if disable_with = options.delete("disable_with")
+	          message = ":disable_with option is deprecated and will be removed from Rails 4.1. " \
+	                    "Use 'data: { disable_with: \'Text\' }' instead."
+	          ActiveSupport::Deprecation.warn message
+	
+	          options["data-disable-with"] = disable_with
+	        end
+	
+	        if confirm = options.delete("confirm")
+	          message = ":confirm option is deprecated and will be removed from Rails 4.1. " \
+	                    "Use 'data: { confirm: \'Text\' }' instead'."
+	          ActiveSupport::Deprecation.warn message
+	
+	          options["data-confirm"] = confirm
+	        end
+	
+	        content_tag(:button, value, { "type" => "submit", "name" => "commit", "value" => value }.update(options))
+	      end
+	
+	    end
+	  end
+	end
+
+I'll probably update this page as I tweak other things I don't like.
