Logseq Quick Capture od hkgnp

Logseq is an open-source note-taking app (www.logseq.com). This extension allows you to do a quick capture of the web-page that you are currently at and send it immediately to your open Logseq graph.

It captures the URL and title of the page; and if you've made a selection, it would capture that as well.

(Logseq v0.8.12 onwards):
You can customise your quick capture preferences by using the extension options page.
