Plugin will prevent sidebar height to overgrown content height and as a result we got a equalized content and sidebar heights. It is based on javascript that will remove last widget from sidebar while sidebar height is higher than content height. Settings are localized and by default work with Twenty Thirteen theme. Plugin unique settings approach to choose css class for content and sidebar allow us to set it up and use on any theme, and possibly in different ways that was originally meant to be used.
Settings are located in Dashboard / Settings / sidebarAutomizer:
Content Class or ID – This must be content CSS class or ID which will define max height for your sidebar area.
Sidebar Class or ID – CSS class or ID of the sidebar element that contains widgets.
Add extra height to Sidebar – In some cases you want your sidebar a bit higher than content. If that is the case add number of pixels here.
Define Element to remove – It can be aside, div, or whatever HTML element that your theme uses to display single widget. Wrong setting can cause unresponsive script behavior in front end.

Thirteen Colors is the easiest way to customize the colors of the Twenty Thirteen theme.
Twenty Thirteen is bold, but if you don’t like its vibrant shades of orange you’ll welcome the ability to transform the theme in a matter of minutes. Just activate Thirteen Colors, head over to the theme customizer, and adjust the default colors to the shades of your liking. Things are kept as simple as possible; colors are grouped into similar usages as in the base theme so you don’t need to worry about contrast if you maintain similar intensities for each color.
Header images are designed to be abstract art for Twenty Thirteen, so Thirteen Colors also integrates with a neat tool that can generate a custom header image in your colors. In a matter of minutes, you can transform WordPress’ default theme for 2013 into a one-of-a-kind masterpiece that’s visually as unique as your content. All of the little details are taken care of, including the editor styles.
By the way, despite the plugin’s name, there are only eight customizable color fields to streamline the process as much as possible. Twenty Thirteen’s original colors are condensed into these eight blocks, but most of the changes are visually indistinguishable.
