Do you want to know more about the enhancements and other significant changes brought to Site Editor in WordPress 6.3? Yes! Read on! 

Revamped Navigation Bar

Revamped Navigation Bar

In the previous WordPress 6.2 version, a handy navigator was added to the site editor. This made it a breeze for users to pick the specific template or template part they wanted to tweak. 

Now, with the forthcoming WordPress 6.3 update, this navigator is getting a major upgrade, giving users the flexibility to choose not just templates and template parts, but also pages, styles, patterns, and navigation menus.  

This advanced navigation feature is set to make the editing process even more streamlined and give end users an increased degree of control over the customization of websites. 

New Command Palette

New Command Palette

The upcoming WordPress 6.3 version is bringing a powerful new feature to the table – the Command Palette.  

With this feature, users will be able to easily navigate to any specific pages or templates, and template sections. 

So, to get started, users must press CTRL + K on their keyboard (for Windows) or Command + K (for Mac) and input their query. Once the query is placed, then it’s done! The command panel is going to display the templates, blocks, posts, and more. 

As a user, you can easily select an item from the results, and it will open instantly in the web page editor. Thus, making it easy for quick actions. You can also open the command panel by clicking the search icon at the top.   

Simplified Page Editing

Simplified Page Editing

The site editor is introducing a user-friendly feature that makes it easy to select “Pages” directly from the editor navigation menu. 

When a user clicks on the “Pages” option, they will now get to see a helpful list of their most recently edited pages. This, in turn, will allow them to quickly pick up where they left off. Thus, saving their time and effort in navigating the site. 
Create a new page and start editing it in the easy page editor by clicking the “+” button.   



Coming to patterns, two improvements can be seen. They are: 

Managing Patterns in Site Editor

This version unveils a more user-friendly and improved way to handle patterns in the site editor. Now, all your patterns are easily accessible within the site editor. 

To view the available patterns, click on “Patterns.” Here, you’ll find both Synced and Unsynced Patterns. 

Unsynced Patterns are flexible patterns that can be inserted and altered at any time as per your needs. Any changes made to them won’t affect the original pattern. 

Synced Patterns, previously known as Reusable blocks, can be used across the entire website. Any changes made to these patterns will modify the original pattern. All your reusable blocks will now fall under this category and appear here. 

To create a new pattern, simply click on the ‘+’ button in the patterns menu at any time. 

For managing your custom patterns, access the sidebar and click on ‘Manage my Custom Patterns.’ 

Learn About Curated Patterns

With the introduction of the “Curated” filter in the pattern directory, users can now easily distinguish between Core-bundled and community-contributed patterns. 

New Icon in Site Editor to View Page in New Tab

Tailored Image Loading

For the tech-savvy, there’s a shiny new function called ‘wp_get_loading_optimization_attributes()’. This lets developers play around and customize how images load, meeting specific needs. 

Out with the Old

Some older functions related to loading optimization? They’re taking a backseat. WordPress 6.3 nudges everyone to embrace the new ‘wp_get_loading_optimization_attributes()’ function for a smoother experience.

WordPress 6.3 isn’t just another update; it’s a significant leap forward. From the ‘fetch priority’ attribute ensuring your content loads in the blink of an eye, to the smarter lazy-loading mechanism, and the freedom for developers to customize image loading to their heart’s content. And let’s not forget the push towards newer, more efficient functions, leaving the older, less efficient ones in the dust.
