Yoman
I built a Calendr clone for KDE Plasma Yoman is a calendar panel widget for KDE Plasma 6. It lives in the panel showing the date, and opens a popup with a month grid and the day's events. It reads your existing Google Calendar (through KDE Online Accounts) and any events in KDE's KOrganizer. Designed to grab your attention with notifications, an optional full-screen alert, and a literal count down to the event right in your menu bar. Yoman is read-only by design.
