Image TV with crop functionalty and multiple predefined aspect ratios

Hey,

I was asking myself if it is possible with an extra like imageplus or imagecropper to implement visual cropping functionality in the manager and give the editor predefined aspect ratios that one can set (So free cropping mode plus predefined aspect ratios). With image+ I only can set 1 aspect ratio. With imagecropper I cannot use the free crop mode.

Thanks!
