Just to clarify, in Brainstorm one can have 6 marks (M, 1, 2, 3, 4, 5) and for each there are simple keyboard shortcuts to 'Throw' the source item or a clone of it. So one can have up to 6 'buckets' at time to classify items in.

In other programmes one could use tags to achieve an effect similar to cloning, since an item can have several tags which is equivalent to belonging to several folders. Some programmes make it easy to add tags, e.g., by find-as-you-type.

Using marks would not help too much, then i had to go through the source
multiple times to gather all for a target and repeat it for the next
target etc. The File Manager guys figured out the correct solution.
