I walk through a new quality of life feature in Tableau Prep 2022.4 that lets you replace a broken or existing input simply by dragging a file on top of the connection. I also touch on the revamped flow edge graph and its curvy lines, though the practical impact of that UI change is still unclear to me.

## Key takeaways

- In Tableau Prep 2022.4 you can replace an input by dragging a file directly onto an existing connection, which instantly fixes broken file references
- Dragging a file in shows a 'replace' icon, and dropping it swaps the data source and clears errors automatically
- You can still fix a broken connection the old way by editing the connection and pointing it to the new file
- The release adds a revamped flow edge graph with curvy lines aimed at reducing visual clutter in large, complex flows
