Hey guys, I had a pretty good app idea that I wanted to make. I want the app to be a basic .pdf reader, .epub reader, and etc. basically, when one is reading their book or document, I want them to be able to take notes in the margins or post sticky notes (virtual) so they can review them later. I know lots of people that will use this, and it's a little bit different than Evernote and all those other note taking apps. I will sell it for $.99, but I want to know where to start. I know I can use corona SDK, and I'm a BEGINNER so can you advanced people please help me out. I also want to be able to open the app on an iPhone simulator ever time I type in a line of code so I can do trial and error. Any ideas on where to start, and how to do it are greatly appreciated. Thank you all in advance.
