Group/Cull feature to have ability to filter/group by metada or visual content to weed out differnt types of groupings faster and more accurately such as focus stack/panorama/interval/burst/composition.

What problem do you see this solving?

Speed up group/culling feature and make it able to search different types of groups and make it find specific types of groups you are looking for.

For example, I might want to search and group images that were made with an automated focus stack which would have been taken within seconds of each other, another group may be the same composition but taken over the space of, perhaps 30 minutes with random time stamps and camera settings but same composition, another may be a panorama, which also likely have similar timestamps compared to other images in the shoot, but not as fast as an automated focus stack.

So if Capture One could be selected to search for groups based only on the grouping of the time stamp in metadata, rather than image content, it should be a fast search compared to Capture One having to build a database of the image visual features. There could be an option to find different groups such as 'bursts' or 'similar timestamps' or 'visually similar' or 'exposure bracket' or many other types of groups.

When was the last time you were affected by this lack of functionality, or specific tool?

This would be useful often. I have tried using 'culling' but the only slider available is a % slider, as I move it around it does not necessarily select my groups any better (eg for focus stacking groups). For example if one focus stack was made directly after another and the composition is the same, C1 does not select one stack grouping from the other. It seems it is grouping more based on image content that time stamp metadata? If the light changed during the stack it seems to account more for that than the fact there are two consecutive focus stacks
