You’ll be happy to know that Agenda 20 will indeed just show the to-do items in To Do now. We are releasing a beta very soon, and should be available in around 4-6 weeks for everyone.
I’m not really sure what you mean with this. If there is no note, where would the task go?
My recommendation is to have a standard note that you can get to very easily for general tasks. I do this. It’s like a daily list, and I use it for the stuff that comes up each day that maybe doesn’t belong in any project. More like reminders.
This is a common request. We would like to do this. Thanks!
