Personalise your own website, no matter what theme and what customization options are added by the themes creator.
When active, the plugin will add a new section to your Customize screen entitled Simple Customize, containing input fields for various elements needed to display a new customize option.
You can easily find what you wish to customize by using the Find element button, which will let you point and click in the preview window to find what you are looking for. 
Although no prior knowledge of CSS or HTML is required to use the plugin, basic understanding of CSS will definitely help you make the most out of this plugin, an in turn your own site.
Once you are happy with everything in the options, use the Add element button to have your customize option implemented. 
The CSS will be queued up in such a manner that it will try to be the dominant rule, so assuming the theme doesn’t have any <a href="http://stackoverflow.com/questions/3706819/what-are-the-implications-of-using-important-in-css" rel="nofollow ugc">!important</a> flags on its styling, your own styling will appear.
You are also able to implement 3rd party fonts using the plugins own options page, where you may add manual styling alternatives, as well as create categories for grouping your own styles.
All customizations are theme-specific, this means if you ever change your theme, you will get a clean slate to work off when customizing it. 
Of course, should you ever revert back to your old theme, your previous custom styling will still be there.
Note: You should always be cautious of modifying other peoples work, respect the time and dedication put forth by your themes author.

WP Login Logo is a simple plugin I made so that I could customise the login screen on my own website by utilising in-built WordPress functions and the WordPress media uploader. 
Considering all the bloated plugins and resource intensive implementations floating around, I thought this lightweight codebase and clean UI could be of similar benefit to other WordPress users/developers.
Don’t expect too many fancy bells and whistles, this plugin does one thing, and does it well.

WP Login Logo

Didn't work, after which I found a nearly identical plugin called Uber Login Logo the worked perfectly fine.  

Turns out reviewing the code for each that this plugin is actually an unattributed copy of Uber Login Logo plugin, only with a couple help screens added (unecessary really) and a bunch of ads/donation request junk added. Pretty shady.


Didn't work, used the older Uber Login Logo instead and it worked fine.

This plugin is a simple, lightweight WordPress plugin to change your login logo.
