bojidar_bg, Oh no! I seem to have missed #libremonday yesterday!
Regardless, my slightly-delayed shoutout of the week goes to.. @thunderbird! With support for multiple inboxes, calendars, contacts, and (best of all, IMHO) RSS/Atom feed (and even XMPP), it's great way to reassert control over your inbox and newsfeed, and not be subservent to Google's innocent followup reminders or social media's incessant infinite-scroll content. 🎉
All of that available at your nearest package manager! 📦
