Use HTML semantic elements to set the landmarks of the page.
This is helpful for assistive technologies to determine the different regions of content. In our case it's useful for jumping between the different islands that we use to group the form controls.
Improve the accessibility of our modals (the color picker and the export dialog)
Implement a focus trap so that tapping through the controls inside them don't escape to outer elements, it also allows to close the modals with the "Escape" key.

* Label and keyboard shortcuts announcement
* Refactor common props for ToolButton
* Better doc outline and form controls
