This will be in the next version. The next version’s interface is undergoing major changes, most of which are yet to be written. Having said that, what I call proximity groups will look something like this:
In this example, the proximity is 1 hour. It could be practically anything at all, which the user will be able to define themselves within reasonable limits.
My intention is that grouping the photos/videos like this will make it easier to assign job codes to them. Job codes will be able to be assigned to sets of files before the download button is clicked.
