Many thanks for your feedback! Well, probably it makes sense to leave the sidebar open for the desktop.

I cannot actually understand how "difficult" is to see the navigation button. Which screen size do you have it? I noticed that it is small for a mobile phone and I need to fix it, but in both 13" and 27" I am able to see that clearly! 🤔

Then, I also thought about Night mode, but it may be a problem with all the colors of the drawings, therefore it may be hard to overcome.

Anyway, thank you for your feedback, appreciate that! I hope you'll find these illustrations useful 😁
