To import or export pdf files takes too many touches to perform. I would say Notability has mastered this.
Being able to export to more than 1 apps. As of the moment to export a file, the file will compile all the pages and will only allow you to export to one applications, and if you want to export the same file with the compiled pages to another app you have to repeat the process and compile the pages again.
- It would be great if you would keep the menu to export until we want to exit out of it.
