Thanks for the suggestion. But I think the app is too simple for that right now. I will continue to improve the app anyway.

Confirm the cropping by double-click is supported now. Thanks.

Thanks for the feedback.

1. The icon buttons are labeled by its `title` attribute, may be not conspicuous.

2. Tap the `Enter` key on the keyboard can also confrim the cropping (Confirm by dblclick is also supported now).

I will continue to improve the app. Thanks again.
