Personal collections of archive.org items

[el4ctr0n]

Dear developers,
I would like to suggest a feature.

Context
An archive.org user having a lot of bookmarked items. Considering that people tend to be interested in specific topics, it's more than likely that a given user's bookmarked items can be organized into collections, for example, "research project", "periodicals", "learning French" etc.

Proposal & Constraints
I see two ways this could be implemented:

1. a folder system, where the user is able to move their bookmarked items from the list of ungrouped bookmarks (the user can only put a given item into a single personal collection).
2. a tagging system, where the user can attach multiple personal tags to a given archive.org item, so any given item can be part of multiple personal collections created by the same user.

Personal collections are only visible to the user that created them.

I appreciate you considering my suggestion.
Thank you for your time.
