Untitled Android PDF Reader

Minimum Viable Goals:

• Continuous Horizontal Scroll - unreasonably rare feature
• Presentation View - i.e. show on an external monitor - haven't seen another app do this yet!
• Immersive View - no system status bar etc.
• Autocrop margins
• Open files the Android way
• • Accept intents to load a single PDF
• • Built-in file browser with requisite permissions
• Delete+Reorder Pages - doesn't have to save the source file, but does need to save a change journal
• • Tap thumbnails in Home fragment to (un)group with previous
• • Tap thumbnails in Gallery fragment to (un)hide page groups
• • Drag thumbnails to rearrange pages
• • Save metadata of these actions between sessions
• Text Annotations - as above

Stretch Goals:

• Networked View:
• • send PDF file to another client
• • synchronize views for different readers
• • coordinate views for one reader multiscreen
• Pen Annotations
• Autocrop undesired elements (e.g. logo in top right corner, copyright footer)
• Improve overall UI
