https://make.wordpress.org/test/2023/05/18/fse-program-testing-call-23-rapid-revamp/

The various features being asked to test in this round are:
– Preview block themes
– Rely on revisions
– Content and template editing
– Using the command tool

Going through the call for testing Full Site Editing program is a very good way for really any user of varying knowledge to go through a guided approach to try out new features. One is shown how to test out a feature and has a chance to give feedback to the experience. Because this is at a very early stage it makes it a lot easier for developers to go in and adjust any feature where it is needed based on the feedback received.
