Import by copy or by move#17

Description
When I’m importing, sometimes I want to copy, sometimes I want to move the folder/files.
So I can either keep an original, or move it to the YNAW a folder.

Current behaviour
Import does a copy

Expected behaviour
You can choose which type of import you want to do.

3rd option available is to have them in both folders with just a single file. Not sure what we would call this from the UI though.

1. Import copy
2. Import move

3. Import shadow copy, Import reference, Add to folder

   -> Will probably have to explain whichever one we choose from 3.

This is done.
I haven’t done the shadow copy, but if I get requests I will add a new ticket for it :)
