Possibility to organize bookmarks in folders

Hello :)

I would like to have the possibility to organize my bookmarks into folders, so that I can use presentation mode for a single folder and not show the other bookmarks when clicking through the report. This would make it possible to have a bookmark folder for e.g. a customer, and only use the bookmarks for this customer in the presentation. It should also be possible to organize and re-organize the bookmarks, so one may be able to change the order of the bookmarks when presenting.
