Hide solo meetings from the menu bar

You can now choose whether meetings with no invitees show up in your menu bar. If you use calendar events as personal reminders or time blocks, you can hide them to keep the menu bar focused on real meetings.

Open the menu bar, go to Settings, and toggle "Show Meetings with No Invitees." It's on by default, turn it off to hide solo meetings from both the meeting list and the menu bar countdown.
