Sometimes I mess up, and fixing it is beyond obnoxious. It really is quite a pain to have to create a new note, select the template, make the changes, save as a new template (with a new modified name because you can't have two files with the same name) save as a new template.
I love using templates, and most of my notes are structured within a core set of them. It's such a great feature, but not being able to edit the templates outside of this process is hard to understand.
