I received this comment on Xiaohongshu. I don't know the app well enough to leave a good response, so I will write it here and post screenshots there.

I mostly use my Traveler's Notebook as a wallet. I like that it has accessories and that one of those is a pouch. I don't like card sleeves for frequently used cards like IDs or debit cards. The sleeve gets stretched out, and the card degrades more quickly. For this reason, I use the pouch and a small binder clip to keep the cards together in the pouch.

I use it as a breadcrumb for my attention. In the event that I get distracted, I don't need to remember what I was thinking about, just like how the top of this page shows you the page that came before it. I do not review this on a monthly or weekly basis or anything like that. Retracing my steps to find where I was is a form of review, and it makes it pretty clear to me when I've gone down the same path of distraction as I did before.

Here, I sketched down the general orientation of an enclosure I was designing. My brain kept flipping the orientation, so rather than try to remember it, I wrote it down. During this task, my brain generated all kinds of thoughts about other things I'd like to do -- like build an extension for Reminders that enables you to associate costs with tasks for help with realistic planning. It's so easy for me to drop what I'm currently doing and start investigating how to make that happen. It's wiser for me to leave a breadcrumb. if it's important for me on my journey, I'll find it and pick it up again. I'm still interested in this feature, because I still struggle to budget in a way that actually works for me.

This is not always a useful tool or approach. Tasks that require me to use get my hands dirty make the flow of reaching for the notebook a bit more cumbersome. Tasks completed near water, like doing the dishes or bathing pets, are also not well suited to this solution for managing attention.

Using this tool in this well is well-suited to tasks where one's hands are clean throughout the task and where having a visual representation alleviates mental effort. Activities like design, programming, and planning are some examples. Homework may be another example, depending on the classes you take. I do not like having to reach into my pocket to make references, so I prefer to use this tool when working on sedentary tasks. For tasks that require frequent hand-washing or movement, I prefer to rely on my watch.
