Thank you to everybody who took the time to write!
I appreciate the detailed instruction , JayJ.
When I first turn on my Nexus, Agenda Plus tells me what is on my calendar for that day, which is great.
I also like Google Calendar to show the month, week or day. What I don't like is that Google Calendar sends an email telling me what the schedule for that day is but most of the time it shows "no events" when there are a number of them.
This was the only part I had hoped to disable or remove. Now I see that this is not possible. So, I will just have to ignore the "no events".
Most of all, thank you for your suggestions!!
