I walk through the enhanced workbook optimizer in Tableau 2022.4, which now lets you act on its suggestions directly. I show how to ignore flagged items so they pass, and how to apply fixes like removing unused fields with a single click.

## Key takeaways

- The 2022.4 workbook optimizer lets you take action on suggestions immediately rather than just reading them
- You can ignore a flagged check to move it into the passed set, but this is a workbook-dependent setting you must repeat per workbook
- Clicking the gear icon on a suggestion applies the fix automatically, for example hiding unused fields
- The optimizer only checks the specific items listed on Tableau's documentation page, so anything not listed is not being checked
