Customizer Theme Switcher brings theme-browsing and theme-switching functionality into the CustomizerCustomizerTool built into WordPress core that hooks into most modern themes. You can use it to preview and modify many of your site’s appearance settings.. By integrating themes directly into the Customizer, live-previewing workflows are greatly simplified, and the relationship between themes and theme/site options is clarified for the user.

These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party represents a significant step in moving all “Appearance” functionality into the Customizer, following Widgets. The future roadmap includes Menus, Theme-Install, and iterations on widgets that would allow the Customizer to entirely replace those adminadmin(and super admin) screens for most users. Because the Customizer Theme Switcher plugin does not address theme-install, the admin page (themes.php) is fully intended to remain in use for now. We are proposing to redirect the front-end “Themes” link (in the admin bar) to the Customizer, as was done for widgets in 4.1.
In keeping with the goal to avoid back-end functionality changes, theme-switches are accomplished simply by leveraging the existing ability to pass a theme as a URLURLA specific web address of a website or web page on the Internet, such as a website’s URL www.wordpress.org query arg when loading the Customizer; ie, the Customizer is simply reloaded to preview a different theme. Loading overlays are leveraged to make this process seem more instant. Unrelated 4.2 coreCoreCore is the set of software required to run WordPress.

Core Changes & Merge Implementation Details
As outlined in the plugin’s readme there are several proposed technical and user-oriented changes that are best done as core patches (mostly in the merge patchpatchA special text file that describes changes to code, by identifying the files and lines which are added, removed, and altered. It may also be referred to as a diff. A patch can be applied to a codebase for testing.):
Change front-end admin bar Themes link to point to themes in the Customizer (deep-linked).
When a new theme is activated, go to the home page (front end), not the themes admin.
If user doesn’t confirm that they want to leave unsaved changes, remove the customize-loading body class (requires core patch).
Move custom section and control to class-wp-customize-control|section.php in wp-includes.
Merge all CSSCSSCascading Style Sheets. into customize-controls.css, scope to .wp-customizer.
Move .themes-panel-back to the Customizer headerHeaderThe header of your site is typically the first thing people will experience. The masthead or header art located across the top of your page is part of the look and feel of your website. It can influence a visitor’s opinion about your content and you/ your organization’s brand. It may also look different on different screen sizes., adjust JS accordingly.
Merge JS into customizer-controls.js, after the respective object types.
Merge customize_themes_template() into wp-admin/includes/theme.php, at the very end. Make sure that this file is included at the appropriate time as needed when adding the Customizer controls.
Merge remaining PHPPHPThe web scripting language in which WordPress is primarily architected. WordPress requires PHP 5.6.20 or higher (all in Customize Register callback) into register_controls() in class-wp-customize-manager.php.
@designsimply has run four usertesting.com tests (see links in #core-customize), and we haven’t really seen any ongoing issues with the actual theme switcher. It has been difficult to get users to follow our instructions, but when they have used the themes-in-Customizer UI, the interactions have been fairly seamless and as-intended. Further testing could be beneficial after merge, but we think that in-person testing and feedback is generally going to be more effective for this particular plugin.
The exact handling of the themes header display still needs some work – the backwards-sliding works well but the arrows to indicate it don’t. @folletto opened a ticket on core tracTracAn open source project by Edgewall Software that serves as a bug tracker and project management tool for WordPress. to work through some alternative options. Most of the accessibilityAccessibilityAccessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities. The concept of accessible design ensures both “direct access” (i.e. unassisted) and “indirect access” meaning compatibility with a person’s assistive technology (for example, computer screen readers). (https://en.wikipedia.org/wiki/Accessibility) issues have been fixed as well (@afercia please let me know if I’ve missed any), with the exception of the Themes section header, which will happen along with the UI changes there for everyone.
A future phase of this project will explore integrating theme-install in the Customizer and minimizing the distinction between installed and available themes. Due to the larger UI and UX changes proposed with that effort, we’ve decided to hold off on theme-install for now so that the basic theme-switching functionality could be built on a reasonable timeline for 4.2. This is similar to the manner in which the “THX” feature pluginFeature PluginA plugin that was created with the intention of eventually being proposed for inclusion in WordPress Core.
