As the question title said, I would like to know if there is an app for iPadOS where I can put and "clutter" several pages from multiple PDFs on a very big board or canvas and I can freely write on those pages with my Apple Pencil.
Apps like Notability and GoodNotes are only capable to work on single PDF at a time so these are what I am not looking for. I saw LiquidText comes close to this but as far as I saw on YouTube, the app only provides users to grab several portions of texts on a PDF, put on a board, and open other PDFs to grab another portions and make some connections to those previous portions. It is like a hassle to me.
Is there any app that could do what I need? Or is there any workaround to put these several pages of PDF on something first? I also have Macbook Air M1 (Mojave installed).
Thank you.
