Thunderbird's Desktop Calendar Visual Redesign

Still no calendar where “today” is visually distinct. It has the same faded background as a multi-hour event.

Look,at the header image and glance in the middle of the Wednesday column vs the middle of Sunday’s or Monday’s column. Very little visual distinction: you have to ask, am I looking at a long event or the ‘today’ highlight?

Personally, I like the Google design and I bet most users will be familiar with. It works. Do not reinvent the wheel and just make it efficient.

About ten years late to mimic Google Calendar. Was hoping for something new.

Fantastical, Readdle and Apple Calendar have slightly fresher UI that could be good inspiration.

What's going on with those dialogs? Are they real dialog windows with hidden window decorations, or are they fake windows drawn inside the calendar view?

And why do they have what looks like a maximize/zoom button, a "..." menu button and a close button? This is a desktop application – we have real window borders for resizing, real menus for menus and real close buttons provided by the window manager.

I still think we don't have good UI for picking start and end times. Anything that doesn't implement clicking and dragging to set events is missing the best way (In my opinion).

Google does it, I wish they went further. The calendar is a visual metaphor for time, let me interact directly with the visual metaphor, let me drag the boxes, resize them, etc.

Dear writers, please don't give me "## The Big Picture"

How is thunderbird these days? I haven't used it for about six years, but I've seen their redesign and recent work in passing here on HN.

I'd like to get back to having a desktop email and calendar client over using a browser all the time.

So this is a new design, but it's at the design proposal stage and not yet implemented?

They've been talking about redesigning Thunderbird for years now, but I'm honestly not sure I've noticed any difference at all in my actual use.

Is it a full page of text to just say that they implemented the UI of Google Calendar?

...can someone tell me why the hell the macOS traffic lights are indented like that?

Like is this just a mockup I'm not understanding correctly?

I was an Outlook user for nearly 20 years. Switch to macOS last year, and along with that went with Thunderbird. It does need some love, but grateful it existed. I like to look at my monthly calendar, open two events, and compare them. Sometimes, I like my monthly calendar visible all by itself, then I'll open emails to the far left or right, then maybe an event in the middle, or to the left.

In other words, I like them all as separate windows, while I compare websites, notes, on the phone, and then adding or editing all these things while talking to people too.

Making the Calendar view, an the list of emails as two separate windows would be amazing.

Thank you Thunderbird team!

A+ Thunderbird team! We absolutely needed an update. Maybe on the next moon mission NASA will send a functional email client instead of two broken ones.

Just another reminder what people who designs these things do not use them. Probably at all.

Useless left bar - eating space, useless top bar - eating much more limited vertical space, stupid arrows in BL corner without meaning or sense, stupid hamburger menu on the top right corner - because if you don't move the cursor a lot means you are not actually working.
