How to Delete an Item from Compendium Bookshelf (and also from My Marketplace Items)

Is there a way to delete an item from your Compendium Bookshelf?  Like there are items on there that I would have never added/wanted.  But can't find a way to delete them. Likewise, is there a way to delete items from My Marketplace Items? Not a big issue, but I have some pretty extreme OCD tendencies that this is just aggravating...I know....1st World Problems  :-/ Thanks in advance!!

You probably need to put in a help request asking for the DEVs to do this for you. I have an almost pathological need to keep things organized , so I feel your pain. :)  but I also hate to throw away/delete things that I've collected, especially stuff that I've paid for. Having the ability to create folders in the Marketplace bookshelf would help this tremendously. There is already a thread requesting that here , so add your vote if you like.

Thanks for the help!!!  I went to that thread and added my response to help the dev's see we want this feature.
