I often import lecture PDFs into GoodNotes to take notes and add annotations. However, the materials uploaded by professors or instructors are rarely 100% free of typos or layout errors. These mistakes can sometimes confuse GoodNotes AI, and when typos exist, I often end up importing a blank white page and manually re-typing the corrected text using the text or pen tools.

As PDF editing is becoming increasingly important, I would like to suggest adding built-in PDF editing features that allow users to directly correct typos and fix layout issues within PDFs. This would make it possible to view and work with corrected text and properly adjusted layouts, without relying on workarounds such as overlaying new text or images.

Such a feature would significantly improve both note-taking efficiency and AI accuracy when working with lecture materials.
