While it's possible to create/share custom views and saved searches with all users there doesn't appear to be an easy way for Windchill admins to actually set these for their users. Currently users must actively select any custom views and 'show' saved searches to use them.
Please add the following functionality:
Allow admins to 'show' shared Saved Search for users
Allow admins to set default views to custom views and push the new default views to users if they were using a different view. Anyone using on a different view on purpose can easily switch back.
If users are using a custom Home Page in Windchill, allow admins to push the customizable 'public' home page to them.
Add an easy option for admins to disable the "Welcome" page in Windchill for all users. This screen is pointless. Edit: Easy means no custom code and likely using the Windchill preference manager where an admin can set it for all users.
