Using VS2012 and TS 2013.2.1327.0, changes to the element explorer (whether it's adding additional elements or changing properties of an existing element) are not retained if the new/changed element is not used in a test. This is a critical issue with the plugin and has wasted many hours of our time building an Element repository that just gets erased after the project is closed/re-opened. Steps to reproduce: 1. Create a new project 2. Open a new test 3. Click Record 4. Navigate to subject site 5. Without recording any steps, turn on highlighting and add a few page objects to the Element Explorer 6. Save the project, close and reopen VS 7. Note that none of the objects were retained. 8. Repeat steps 3 & 4 9. Record a step 10. Add additional elements after recording a step 11. Save and close then re-open the project 12. Note that the additional elements were retained 13. Now add additional elements without recording anything, then save/re-open 14. Note that the additional elements were not retained because none of the elements were used in the test
