Project mention: Rnote – An open-source vector-based drawing app | news.ycombinator.com | 2024-03-11

I highly recommend Rnote to anyone on Linux that misses the "hodgepodge" notetaking of apps like OneNote. It works like a dream on touchscreens and drawing tablets, with a surprising amount of configuration under the hood.
Also worth noting is Xournal, an older but similar project: https://xournalpp.github.io/
