For people (like me) shooting in some burst mode, it is not unusual to have many very similar versions of the same photo captured across sub-second intervals. Today, tonfotos does not treat these as similar and this can dramatically increase the time it takes to go through the suggest/confirm loop.
It could be useful to implement a “Automatically stack photos by capture time” feature, similar to Lightroom Classic’s feature of the same name that automatically stacks pictures taken within a given amount of time so that all pictures can go through the suggest/confirm loop at the same time (ideally stacked).
