The Textagenda is one of our mid-sized daily planners, but based on the layout I think it’s got much more potential.
At the top of each page is a small timestamped section on which to write your appointments. Below it are 14 lines to fill with… anything, really. You can look forward, and write your goals, aspirations, and to-dos. You can look back and use it as a journal. I suppose you could even use it to write, say, a paragraph a day of a piece of writing? Though it’s perhaps a bit small for that.
There’s also a small blank section at the bottom of each page for notes, perhaps the things you want to prioritize.
The size, at any rate, reminds me of a smallish, but substantial novel, which is perhaps why I think of prose. I’ve never used it as a planner, though I have used it as a notebook, because good paper is a terrible thing to waste.
Here are some reviews from around the web:
