Manage notes in Agenda

I tryied many apps and Agenda is the best i’ve found. Anyway to have a more powerful tool I’d like something different in relevant notes management.
The list as it is now is good but not enough.
I’d like two more logic views: one as in a clendar based on the date of the note and another by tag like it appens in Trello lists. In these views of course would be impossible to show the entire notes so is important to add to the notes structure a subtitle too.
If there are ways to do this already that I don’t know. Please tell me. Thankyou.

Thanks for the feedback, we do have plans to make overviews much more powerful. Not sure we’ll go as far as making a tag or calendar type view, but we’ll keep your suggestions in mind.
