I have cropped the image but the old one is used on the page.

If you had viewed your image on the site before, your browser has cached the image. Go tell them to reload the fresh image from the server by hitting "F5".

I have cropped the image but in the featured-image box in the editor the croped version dont show up

Refresh or Update the editor page.
Note that the image in the featured-image box will only be a preview, to show what image is choosed. The theme defines what image-size is used on the front-end.

Is it possible to crop an non-cropped image-size?

Currently not.

What ideas for further releases you have?

• allow cropping window in frontside
• allow new crop sizes beside the ones added with the add_image_size() function (for using less disk space)
• reset standard image-crop
• let the user generate all image-sizes at once by define a "central point of interest"
• maybe use the new WP_Image_Editor class
• add a option-button for dont use the minSize-Boundary of jcrop
• put editor-options into a collapsible menu
