I've been searching for hours on both my tablet and computer for an android ereader app that has note taking capabilities beyond highlighting text and making a note on said text. Rather I would prefer the note taking to be an optional pop-up window that would allow you to take notes in a more complete format similar to how you would on actual paper, like an add-on similar to the basic functions of "Slide Notes" or "ColorNote" maybe with the ability to make new note pages. It doesn't have to be as complex just somewhere above small markups. My desire is to have an app that I can use when traveling or for convenience to study informative books while taking more complete notes. Does it exist? Thanks
