This works. Thanks!
The only concern I have is whether SQL Developer is designed to handle network or cloud storage of these settings while SQL Developer is open from another location(s). Perhaps it is. It is seems that settings, e.g. a new database connection, don't become available at the other computer until exiting from SQL Developer on the computer where the change was made.
Yes, you'll be fine, mostly.
Files are generally written on application shutdown.
My only caveat, in version 4, passwords won't be transferable, so your connections will carry over but the passwords will not.
