Better zoomed-in gallery functionality

[SmilyOrg]

Is your feature request related to a problem? Please describe.
It's not clear that it's even working as intended as the zoomed in view is very bare right now.

Describe the solution you'd like

A few things would make it better

• Arrow/X icon top left to zoom back out by tapping instead of zooming, perhaps another tap of the photo can also zoom out
• Visible/clickable left/right arrows for moving back and forth
• Support for swiping on mobile
• Action icon buttons on top right or somewhere for common functionality (e.g. download)
• Single image view (not showing photos on the side)
• Image details/metadata (as a sidebar?), maybe this big enough to be it's own issue

I do quite like the current minimalism, it looks like iOS photos, but on every platform. Whatever changes you make, please don't lose that clean look!
