Great app ... But
There IS a front/back camera toggle in the upper right.
There IS a folder icon in the upper left to select pictures on your device.
My sole gripe is that the exposure should be locked between left image click and right image click. Otherwise both are auto-exposed and often require post-processing by another app to correct for exposure.
That retention between left and right should ALWAYS be the case, and should be the default.
Otherwise, a great app.
