Hi @KC Lu - I have been using a local repo that connects to a server remotely, and it works great! Things update simultaneously. The only specific part that always asks me for mismatches is the Storage section on %Persistent classes, as you're mentioning. I will try to use the refreshClassesOnSync config and see if that fixes it. Additionally, where can I find all the configuration options for my .vscode/settings.json related to "objectscript.conn": ?

Great article @Luis Angel Pérez Ramos!
