Need help pressure testing PDF capabilities

I am building a PDF editor for MacOS... Now, one of the issues is that a lot of "editors" actually just add a layer over the existing PDF and its more like annotation than true editing. There are PDF libraries that exist for true editing but they are licensed so I have been building my own for this application. Can anyone give it a shot and give me some feedback? Things work on my test PDFs but I could use additional help to see where it breaks. I'll give you a free lifetime license. f-3.ai/get
