The organization of the app strikes me as a little similar to Day One. However, I can adjust the space between paragraphs. I can open notes in their own window. Markdown can be used!
Specifically, for what I use it for, it's superior to Day One, and I'm happy I made the switch.
I've reached out to the developer twice over tiny issues, and the developer was incredibly responsive. Highly recommended!
Very good A request: When I insert a link to another entry in an entry, I want it to appear somewhere in the original entry in a list, like a trackback.
