I like it. here are some suggestions for improvement;:
1. The magnifier pops up above the finger press, which means you can never zoom in to items near the bottom of the photo - they are zoomed off the screen.
This is also true to a lesser extent of the left and right edges.
To fix this, change the way the magnifier pops up relative to the finger press - base on screen location.
So, if I long-press near the top of the screen, put the magnifier BELOW my finger; now I can see all of the bottom of the image.
If I long-press near the right of the screen, put the magnifier TO THE LEFT OF my finger; now I can explore the left of the image.
Etc.
2. These days, with image quality so good, it's worthwhile and good fun to zoom much further in and see what's there, but the browser only has one zoom level.
Several ways to address this:
a. Have a ZOOM LEVEL setting in the app - currently seems to be 2x, but you coudl then set it to whatever you like.
This option means nothing much else changes and the double-tap to see zommed version still works, and there is no new massive process-intensive burden to deal with.
b. When the magnifier is active, arrange that each subsequent single-tap zooms in a bit more. DIsmiss it with a double-tap.
I realise that now dynamic zooming at arbitrary levels is called for, and maybe the processor can't handle it,
but I would be happy to wait 5 seconds while the app prepares a new zoomed image - it would be very cool.
3. It doesn't seem to understand folders. I want to organise my images into folders, so I can choose which images I shar with which people as they look at my phone.
I don't want the app to flatten everything into a single gallery.
4. Seems more natural in the West to time-order things from left (oldest) to right - but this app odes it the other way around.
5. Like others, I would also like to see richer functionality accesible from this app.
Anyway, nice app.
