Please take a look at this calendar for mobile: https://play.google.com/store/apps/details?id=com.appgenix.bizcal This is what I had before I moved to Proton. I wish Proton would adopt many of its features

The month view is adjustable from a 1 week view to 8 weeks. I used the 3 week view so I could see at a glance each day's "headlines."

The month view is scrollable. It doesn't jump from October to November; it scrolls week by week

The entries in each day are clean - no bubbles around each item, taking up space and looking "messy"

Adding to the calendar is SO much easier!

-There are multiple options for notification time frames
-If I use the custom notification option, it ADDS that time frame to the list of defaults! No repetitive, multi-step additions of time frames each and every time. This is so handy because I often use the same custom option in all my calendar entries.
-There is no default notification added. If I want to quickly add an event with no notifications - DONE!
