Highlights
🔒 🗒️ New in @vimcal: You can now add a private note on any calendar event!
By "private", I mean no one else can see them but you. Not an attendee, not a teammate, not even someone with edit access to your calendar.
Use them for:
- Quick meeting prep, e.g., “Remember to bring up budget increases”
- Running agendas
- Sensitive context you don't want in the description
Just scroll to the bottom of an event on any of your calendars and start typing.
Your notes live within your Vimcal account and are for your eyes only, even if the event is owned by a coworker or is on a shared calendar.
This is a feature I've personally wanted ever since we launched Vimcal in 2020, so I hope you find it as useful as I do!
Comment and let us know if there's anything else you'd like to see regarding notes.

🌐 We've got another new feature for you today that you'll only find in @vimcal!
Now when you look up your coworkers' calendars, Vimcal automatically sorts everyone by their local time so you can immediately see how everyone is spread out.
You can then overlay everyone's time zones onto your own calendar in just one click.
It's easy to forget who is where when you're scheduling across continents (or even just coasts). This small touch makes it a tad faster and much less error-prone =)
