I am an iPad user and frequently work with GoodNotes using an external mouse.

However, I noticed that several tools in the app are not fully supported when using a mouse. In particular, the highlighter tool cannot be used properly with mouse input, which significantly limits productivity for users who prefer or rely on this type of interaction.

I would like to suggest the implementation of full mouse support for the highlighter tool and other drawing features. Adding this functionality would greatly enhance the user experience and make GoodNotes even more versatile for those using the app in desktop-like workflows.

Thank you for considering this improvement!
