Potential for a physical KSP notebook?

IDK where to put this, but I would absolutely adore a physical KSP mission log to write all that stuff you need to jot down somewhere. Something official that had templates pages where you could write the mission name, key numbers, designs, etc. Staging notes to remember, descent logs, notes on how to improve the ship for the next mission. Perhaps a cheat sheet on the inside cover with optimal transfer windows and dV calculations. Feel like it would be an awesome merch idea that would actually be useful.

There is a mod but it is outdated at the time of writing.

No I mean a physical physical notebook. That you buy. In real life.

If you're willing to accept something that isn't specifically branded get you a Leuchtturm notebook or three. I've fallen in love with them for keeping notes for roleplaying games (I prefer the A5 size, perfect for bullet-pointing), really high-quality and a joy to write in.
