Please freeze the "Sun Mon Tue Wed Thu Fri Sat" header in the calendar by month view at the top of the page so we can see the day of the week as we scroll down to the third and fourth week of the month.

It is very difficult to view the calendar at first glance. I have vision issues, as I expect many users do, and having the option of adding gridlines (such as what is offered in Gmail) would be very helpful.

Hovering over the message and seeing the "*** to Calendar" option makes it more difficult to open the message and read it. Currently, users have to click on another field like sender name to open a reminder message. If you click on the Add to Calendar currently, you get a prompt to put it in one of the calendars. Instead, wait til the message is open and than allow the add to calendar if users click on that button.

List View on desktop made it easy to look at a full month and review events with minimal scrolling. Doubly so since I could see all the full event names, and zero in on the ones I need to view, without having to first click for additional information -- especially when the event I am seeking isn't visible from the date square, thus requiring repeated down-arrow clicks to show more date-after-date.* Failing that, please add the ability to hover over a date and see a list of all events for the date -- hopefully with this hovering producing a list for that date that is much wider than a calendar square.

*EDIT soon after posting: I see you had already added an option to automatically expand a date's box vertically when needed to display all of that date's events. That's a bit of progress, but leaves most of my suggestion unchanged.

You really need to restore option for List View of events in Calendar. That view, which you have now removed from both the "standard"/old and new Mail viewing options, is the only one that works for me. Deleting that option will push me to other mail/calendar sites and tools.

Please bring back the "List View" in the Yahoo Calendar!

First you removed being able to see Calendar reminder custom icons in Monthly view (to only have it in "list" view), and NOW you have eliminated "List" view. Why do you have reminder icons at all???
