#FreeSoftwareAdvent day 1 catch-up (what, it's December already???)

I'll start with a recent project called #Papra which I love for its simplicity and nice UI. It's a document archiving solution, which keeps it simple, but still provides:
- a nicely executed tagging system
- auto-ingestion of documents by watching a folder
- ingestion of email attachments via the twin project #owlrelay by the same author
- in-page document preview
- API and webhooks triggered upon creation, modification...
