Adobe Reader (Android) missing features

It is a very effective tool to work with checklist form on a tablet. It works much better than Excel sheets on mobile devices. But why there is no function "Save As" like in the windows version? Prepared forms are modified by just closing the app without any choice to save it under a different file name. Futheron there is no file manager function for easy access to the @work folder. Still there are locations without internet access, where local file management is needed. I understand the cloud preference, but it doesn't work everywhere and should be still a choice of the user.

Adobe forms with Adobe Reader on mobile devices could easily be first choice for inspectors and technicians to improve their daily job. Just add some functions, that are already part of the windows version.
