On OneNote I have 14 different colored pens and highlighters up top. GoodNotes is superior to one note in almost every way except this one. I color code my notes, so I am forced to used one note. If I were to try and color code using goodnotes, it would take me hours longer because there are so many extra clicks to get to the correct color of pen or highlighter. Having more color options up top and allowing both pens and highlighters in the menu bar like one note would be amazing.

There is plenty of room up there, changing pen thickness is not important enough to have that much space up top, other colors are. But honestly there is plenty of room for more colors, you could just shift the thickness all the way to the right and the other menu options all the way to the left and have room for 10 more colors.

Often the pdf documents have ~1" margins and there have been paragraphs that I would either like to add my own commentary, create a small sketch of an idea, or note an idea related to the material. The margins aren't big enough to fit, but adding a whole blank notes page is too large (I use an iPad Pro).

I request a feature for having a color indicated "sticky note" that fits on either side of the margins and can be placed anywhere alongside it. Tap the little box, and the expanded note comes into view with various options for text, changing note color etc...

Truth be told, the text zoom feature interface that is already in place would work fantastic for this sticky notes feature.

If there could be a tray where I can add 4-5 various colors of pens and highlighter mimicking a real physical object that I can just pickup and write. For example, I could add a red colored pen with fine thickness, a black colored pen with bold thickness, yellow highlighter pen with certain thickness and automatic straight line.

In that way I can jump between each tools and options without having to turn on/off auto-straight-line function or adjust the thickness every time I change a writing tool.

You can let this function to be optional that users can toggle on/off in settings if you are afraid that it will complicate the app too much.

would love to see more mathematics tools such as a ruler, a pencil compass, a real life scale on the paper, and maybe even a calculator within the app. Maybe a calculator you can move on the screen or click it with your finger to summarize an easy equation? I bought an iPad intending to only use your app for all of my notes when I go into college now, but unfortunately I do not see myself using this app for mathematics just yet. Pie charts, gifs and videos in the notes would also be very helpful. (I could for example film how my teacher did an equation or a lab experiment and simply paste it into my notes) it would also be very nice to have the opportunity to use premade symbols in your notes like arrows etc.
