yugutou Thank you for your feedback! I think this is a good point, but I think using the Sync
button might be sufficient instead of adding a new feature. Have you tried using that button?:

It's not exactly a feature to zoom in on the Loop Start and End ranges, but it should be useful for aligning the zoom level displayed in the dopesheet with the range displayed in the graph.
However, I think it might be nice to have a hotkey or something to automatically align the zoom with the Loop Start and End ranges. Would you like to see such a feature? Or is the Sync
button sufficient?
