Downloads a .xpi file (0.04 MB). In Zotero, open Tools → Plugins and install it from the file.
In useAn estimate of how many copies of Zotero have it: Zotero downloads each new version once for every copy that has the plugin, so we count the downloads of its most-downloaded recent release. Rounded. Plugins that update from outside GitHub count low.

What it does

Written by AI from the README

Adds several personal libraries side by side in the collection tree, each working like My Library. Each has its own collections, searches, tags, trash and duplicates. Drag items between them. Extra libraries can stay local or sync as a private group. Needs Zotero 10.

A Zotero account has one personal library, so separating work, teaching and personal reading means group libraries or a second profile. This gives you separate libraries in one window.
