Any plans to add Evernote style templates? I would really love to see this feature.
Yes, templates are certainly on the roadmap. For now, you might try TextExpander, or simply setup a note as a template and copy it.
I use Typinator for templates (same idea as TextExpander) – what I like about doing that is that I have pop-up dialogs configured for each template that opens, I fill it in, and then the whole formatted result is pasted into Agenda. (Or Notes, or Evernote, or wherever the note is going.)
