When working in project mode and collaborating via a version control system like Git, remember to restart 4D to apply any changes made to the catalog.4DCatalog file. For example, Alice makes some changes to the structure, and pushes the catalog.4DCatalog updates to a remote repository. Bob pulls these changes to his local project. If Bob already has the project open in 4D, he would not see the changes to the structure until he restarts 4D.
