org-roam-tree.el is exists to help mine a knowledge base in an Emacs org-roam Personal Knowledge Management (PKM) system. Across thousands of files of research notes and reading annotations, it helps to unearth different authors’ takes on a topic, find unexpected links between topics, and create knowledge from your research.

It adds a tree-style backlinks view to your *org-roam* buffer. Backlinks are grouped by their source file, with optional “crosslinks” — other nodes that a backlinking node also links to.

A modern port of Jonas Bleyl’s Recurrence Android app, rewritten for compatibility with current Android APIs and policies. It’s an intuitive notification reminder app: repeat reminders daily, weekly, monthly, or on specific days; control exactly how many times a notification fires; add icons and colours; and create nagging reminders so important things can’t be ignored.
