有一点小问题

荧光笔的方向不会随着pencil的转动而转动，并且每次方向是随机的，想要调方向就要转动笔的朝向，不太好用。

One Suggestion

I love everything about this app so far. I am a heavy users of GoodNotes and MarginNotes. I use both of the apps for note taking and study. What I like about this note taking app is it’s user-friendly, it has a white board for mind mapping, and flashcard for studying. I did not get to test white board and flashcard to study yet but this app is very promising.

One suggestion I have for the developer is if you could allow Apple Pencil to be able to transition from one tool to the previous tool used. The current default setting is it switch between pen and eraser. But for me I rarely use the eraser because you can undo with two taps. I switch my pen a lot more from black and red so it would be huge if you can do that here.

Thank you for the amazing work! and thank you for taking the time to hear my feedback!

Perfect for me

So happy to have found this. It just works exactly how my brain does. Love the weight of the pen stokes, the simplisity, the nesting of notes. Really well designed and considered app - Perfect for me and rare not have a subscription model. Love it ❤️
