When I'm looking at planners, a row of habit trackers feels less useful than a decent bit of blank space beside the weekly layout. I can use that space for changing plans, little reminders or the odd sticker, whereas empty tracker boxes just make the page feel cluttered. With a monthly budget, I'd rather pay for pages I'll actually use than extra sections that look good in the listing.
Yeah, blank space is more use to me too. One tracker for a habit I keep forgetting can help, but give me a whole row and I start ticking boxes for the sake of it, which tells me nothing.
