I've been using Hey Calendar since the day it was released. I have completely switched on Day 1. I love the design and many of the features. Here are the few things I'm missing.

A feed of events would help integrate into other tools. Personally, I'd love to add my personal Hey calendar into Dato and my work calendar (on Google Workspace).

EDIT: It turns out that this feature was released recently.

I wish I could keep my emails and my calendar open side by side on the mac. Switching from one to the other within the same window is annoying. If I'm sending an email about an event, I often want to double check my calendar and it's not very nice. Maybe it can be Hey with both (with the switcher at the time) and a dedicated calendar app alongside.

EDIT: You can `CMD + Shift + N` to open a new window: one on email and one on calendar. When you close the app and start it again, it will re-open the 2 windows! 🤩 Thanks @andrewcgregory

I don't mind the day view being horizontal, I kinda like it. I just rarely look at the day view on a desktop because I don't have that many events in a day. I keep clicking the week button, I wish it was the default.

EDIT: There is now a smart navigation that remembers your last view. 

I'd love to repeat task every first week of the month. There are some chore (buying ETFs for instance) that I cannot automate and I have to do each months. It doesn't have to be a specific day but it has to be around the same time each month.

I absolutely love that you can name days and add photos. This is probably my favorite feature. Now, I kinda wish I could see the entire year like this. Not an infinite list of dots showing that there was events every days. I don't care about my doctor appointment or a reminder that I had to do something on the 7th of May at 10:15am.

Instead I'd like to see a nice summary of my year with all the happy events: birthdays, family weekends, trips, anniversaries...

Here is an example of how I did it on paper in 2017 and 2018.
