Improvements for writing tools!

I did a survey with my team to see how they would like to see improvements to the charts app and here were some of the reoccurring ones.

1. When writing with Apple Pencil, the pencil should be registered as writing tool and the palms should be rejected.
2. The writing in general feels very off and irregular, or just wonky and not smooth. - The 90% of the members decide to screenshot the chart and just use their own writing app. Which is a huge issue because it means that if during practice we make changes, they do not receive the same real time update benefits.
3. Would love to select writing and copy/paste
4. Erasing doesn't work smoothly. Currently you have to select an area and 'delete', rather than erase like a traditional eraser.
