Cropping should have a click-and-drag feature

In my workflow, I have to do alot of image/video cropping, and I find it frustrating that every time I do it, I have to go either into the properties or effects control panel and nudge numbers, instead of just dragging the left/right/top/bottom pins of the frame (like how you would resize a image/video). 

If, let’s say, I click on the “Motion” tab in “Effects Controls”, and I press a hotkey (ie. Alt or Option) and click and drag one of the left/right/top/bottom pins, that would crop the image/video.
