Hi Hasib,
We are going to introduce a wide range of features for project management on the platform over the next 2 releases. Here is how it works as of today:
1. All artifacts that are part of the "default" project are shown regardless of which project the user has selected to be on. This is to allow the reuse of artifacts between different projects. A simple example is an LDAP common login for all applications in one organization.
2. The point of not showing the locator in the drop-down in step authoring is to give a hint as the locator doesn't belong to the current project. However, we think this may be confusing to some users, so a ticket has been created to provide users more info to avoid confusion.
Regards,
Subject7 Team
