An option to have a radial/floating menu of favourites like different pens (with set color and size), lasso tool, eraser, highlighter, etc. that can be pulled up with custom gesture like long tap with finger or the double tap on the Apple Pencil.

As a student, who frequently needs to switch between different pen colors and sizes, always having to reach up for the menu bar takes time and so a shortcut that can be accessed directly where my pen is would be incredibly helpful. Even just switching between two different pen sizes with a gesture would help a lot.

Goodnotes is my favourite note-taking app and I really love how you ask for and actually implement user requests. Thank you for all your hard work.
