Please consider adding this sooner rather than later. I can't imagine it's very difficult to implement. Coming from Google, I use calendar reminder emails to basically manage my life. They are my to-do list, my reminders, etc. Not being able to see the event title in the email subject ruins all of this. Now I have to send myself manual email reminders AFTER I get the Proton email notification in order to make sure I don't forget things.
