   - for the workspace scope, go to the Plug-in Development > API Errors/Warnings preference page.
2. Select the tab for which you want to modify an option:
   - API Use: for options related to API usage (unsupported tags, API restrictions, API leaks)
   - API Compatibility: for options related to compatibility issues. They are sorted per type of element
   - Version Management: for options related to invalid, missing, malformed @since tags or incorrect plug-in versions)
   - Analysis Options - for general options
3. All options of a page can be reset to the default values by clicking on Restore Defaults.
