I might be one of the few people here using the images-function in mc.
However, look at this example of pictures with different tags/sub-tags
---
imgA, tagged: Christmas
imgB, tagged: Christmas\Eve
imgC, tagged: Christmas\XDay
---
In MC, as it is now, it will look like this
---
Events:
Christmas
- This Folder (contains imgA, imgB, imgC)
- Eve (contains imgB)
- XDay (contains imgC)
---
So. The problem is, MC auto-checks "Christmas: This Folder" for all tre three images. My opinion is, only imgA should be in "Christmas:This Folder".
Otherwise, there is no use in having the "This Folder"-line in the Events-list, since I can mark the root line "Christmas" to see all christmas-pics.
Hope I made myself clear enough.
