[is Crop to selection possible]

Thanks to all of you,
 

I discovered that for my actual workflow the destructive cropping-procedure can work like this:
Crop the image, make a selection round what is needed to be stripped down, copy this - and then I used via the main menue "Edit/ make reduced copy" (not sure how the english wording here might be). So then I have a new layer with the desired cropped object.

Hi all,
 

and my first post goes here.
Which is also a plus one for the crop to selection - functionality.

Also coming from Photoshop (where it was so dead-easy to do), I'm just wondering - after having had several situations where I wanted to do a simple crop and resize and then fiddling around and thinking "hm, there has to be a way to do this in a simple matter". And then I searched, searched and finally found this thread : )
Ok, I will manage to use some of the given tipps and workarounds here... so thanks! Nevertheless it should be possible to have that option.
