Hey @Capybara,
The search bar is always there, I recommend looking at some good examples of nbs to start. However, to answer some of your questions directly:
No. It really depends on what works best for your team. Just make sure that there are plenty of relevant visuals and information that accurately documents your edp.
From my own experience (IMO), it really helps to have a title, page number, and date though (correlating with toc). Try to not have a huge block of text. It’s an eyesore. Make sure to make important information easy to be found by highlighting, bolding, etc.
This (again) really depends on your team, but IMO sans serif is better, it’s easier to read and interpret quickly. Like found in studies:
Lastly, good notebook examples are 515R’s (Worlds Design): 515R Spin Up Notebook - VEX V5 General Discussion / VEX Robot Showcase - VEX Forum.
Another one is 8926W (Worlds Excellence): 8926W High Stakes Notebook - VEX Robotics Competition Discussion / VRC - VEX Forum
and 5203G (Worlds Excellence I believe): 5203G gremlin notebook link - VEX Robotics .Competition Discussion - VEX Forum
Most of all, look at the rubric like @kkaidenn said. If you want to know what judges like, the rubric is what they are literally looking for: Judging Resource: Engineering Notebook Rubric – RECF Library
Good luck, and have fun!
