More tool or customizable annotation tool

I often use straight and free-form pen tool and highlight tools. Currently, we have a sub option for each tool to change its straight and free with detailed options.

In addition, why don’t you give them the option to add a few user tools to the toolbar?
An app called flexci reflects this demand well, so I put the image as an example.

Hello, havewisdom.

Thank you for your suggestion, we have received many similar comments about the design of the markup toolbar and are still discussing the details of the implementation.
