As the Site Editor and WP-Admin get more and more features, the need to navigate quickly and efficiently across them is becoming increasingly important. Visual editors and code editors alike are adopting the command center as a solution to this problem, with examples such as Visual Studio Code for desktop applications and Notion in the web applications spectrum.
Prototype
Initially proposed as part of the WP-Admin experience revamp post, an early prototype of a command center has now been implemented as an experiment in the Gutenberg plugin, starting in Gutenberg 15.6. Once enabled in Gutenberg > Experiments, you can navigate to the Site editor and hit the cmd + k (or ctrl + k on Windows and Linux) shortcut to open the command center, run commands and quickly access frequently used actions.
