Symbolic links within a collection tree
I use the collection tree to order my records because I find that the tags are unmanageable with a large dataset. Often I find that a particular issue or sub-collection needs to appear in more than one tree. It would be very useful (and significantly simplifying) to be able to link a virtual subcollection to an existing one. (It is possible to link standalone notes, but the link takes place outside of the collection tree.)
I.e. I have the same collection - say "Articles on Zotero" - and want it to appear in "Open Source Software" and "Academic Software" - is that right?
