I wonder what software would be good for a logbook like this... I just use google docs for these kinds of things. Sure wandb and jupyter notebooks are good but they are not so good for notes and ideas and documentation
Sometimes the generic solution is just the best. No one requires special training on Google Docs and it just comes with handy features like version control and live updates.
Personally I use notion for this. Not dedicated software, but the extra options in formatting/structuring and linking can make a document like this a lot more readible.
