I would love to. The most cumbersome thing about notebooks, even larger ones like A3, is 1) they dont lie flat, and 2) even if (eg. rings) when I want to write on the left page, my hand hits the "spine" between the pages and its not comfortable writing.

When I used paper I got used to have a stack of A4, put a title in one corner, I?d keep them on my left beside the keyboard. There are nice a4 in 4 light pastel colors, easier on the eyes than white, and simple memory cue when looking in the pile.

I’d have cheatsheets and tasks, the task/feature pages with lots of check boxes. I’d keep some cheatsheets for a long time, like css/typescript, and the task ones i would throw away when that feature is done.

I use the right hand pages only. When I get to the back I flip the book over and, starting from the back, continue using the right hand pages that were formerly on the left.

I like memo pads, something like this: https://www.jetpens.com/Tomoe-River-52-gsm-Paper-Pad-A4-Blan....

Just stating the obvious. All people writing with a fountain pen know that writing in notebooks of any sort is more pleasant when said notebook is rotated 90 degrees, with its spine going across. From left to right.

Then, the angle of the paper to the tip point does not vary across the line.

Surely you mean 45°? 90° is rather extreme.

Not if you're writing parallel to the spine.

The ones I use are like 4 inches by 5.5 inches. Really tiny. Easy to deal with.

Sewn bindings will lie flat if the book is thin enough, like 100 pages.
