So I'm trying to make an effort to throw out all the various writing programs I use and try to exclusively use Ulysses and Movie Magic Screenwriter. I wanted to share with you my latest victim known as Journler.

Here's what I'm trying. My project is titled Journal. My documents will be titled with just the date. My notes will be just quick little points such as things I did for the day and/or accomplishments, or perhaps a to-do list. Project Notes I'm setting aside for my longer term goals for the month. At the end of every month I'll export to PDF and begin again.

What are your thoughts? Can you see this back firing in anyway?

One thing I'd like to do is be able to implement a tag within the notes. For instance, if I accomplish a goal I'd like to be able to strikethrough it.

Any other ideas?

You can do the strikethrough directly in the notes, there is no need for an additional tagging system there. The notes are rich text so (I think in the font panel) you can just apply a strike through to your achievements.

One easy way would be to show the Ruler (Format > Text > Show Ruler). Struck Through is one of the Styles you can chose in the Ruler.
