** Describe the feature request below ** I feel that the image viewer's behavior should match the behavior of other apps, with the biggest issue being the lack of swipe to discard which in somes cases allows the image to go off screen in the current viewer (0.0.33). In comparison: Fully viewed out:

• Sync/Relay: Gesturing up/ down or tapping anywhere (on or off image) discards image
• Boost: Gesturing up/ down discards image tapping anywhere (on or off image) hides/shows navigation
• Jerboa: Gesturing up/down does nothing tapping anywhere (on or off image) hides/shows navigation

Partially zoomed in:

• Sync/Relay: Panning left/right bound by image Gesturing up/ down discards image
• Boost: Panning left/right bound by image Gesturing up/down does nothing
• Jerboa: Panning left/right bound by image Panning up/down image can go partially off screen.

Deep zoomed:

• Sync/Relay: Panning left/right/up/down bound by image if image hits top or bottom of screen, further gesturing swipes to discard
• Boost: Panning left/right/up/down bound by image Gesturing does nothing
• Jerboa: Panning left/right bound by image Panning up/down allows the image to go off screen!
