more options for pens
A greater variety of colors for pens and different typs of pens and opacity would be very nice.

Would be nice to at least enter hex/ RGB value for a custom color, but would also like to see color picker.
My use case (I'm a management consultant for what that is worth) - mocking up a wireframe or other visual for change management, I would want to use my client's color palette so it is the "right" shade blue and not just a generic blue.
This is so close to being the perfect tool for fast lightweight sketching. Just needs a broader colour range and customisable nibs. An inking or calligraphy brush of some sort would be brilliant.
We can't have a pencil? A pencil that we can change colors on like for redlining a drawing? You took away Windows ink and left us with this giant garbage maker stuff?

having same/similar options as you do in OneNote would be great.
or at the least let us use a colour wheel to choose more vibrant colours.
the default don't stand out enough.

More than 1 highlighter.
thicker lines, arrows etc would be great
