I would be very nice to be able to have more than one target collection – fx 10 – accessed by CMD or Ctrl 1-9. I often come home with many pictures, and when I want to sort them I often use collections – fx landscape, flowers etc. The problem is that I have many folders and collections, so my current method includes a lot of dragging, dropping, and scrolling – and it is not very easy – actually it is often confusing. A hot key for my most used collection would be great. Maybe it could be made just like the keyword set.
