Components
teksfairy is an application that converts images to text, images can directly use the camera phone or from the gallery, improve the viewing angle of the image, edit the extracted text, extract text extracted into the keypad, and can convert the file into PDF.
Proposal
My suggestion for the development of this app in order to add features "starred" this feature can be located above (beside the camera feature).
Mockups / Examples

Benefits
The benefit if the development adds this feature is, the user can mark important files or the user can quickly find their files. With this feature the user does not have to scrawl the document down, And with there features that users will not hesitate and afraid will lose their documents.
I'm sure if the feature is added it will make the user more comfortable in using the application.
