How can I rename the common prefix of multiple translation IDs?

When working on large projects, it's a good practice to organize translation IDs using a hierarchical naming scheme, such as:

translation ids with namespaces

To rename a common part of multiple IDs (e.g., the validation part), you first need to enable namespace support. Open the Configuration dialog and set the JSON format to one that supports namespaces:

select json format with namespaces

In this mode, a small icon appears at the top of the Translation IDs view, allowing you to toggle between a flat list and a tree view. In the tree view, you can easily rename folder-like nodes (representing prefixes) by right-clicking the folder and selecting Rename:
