Hello. In the Library mode, would be nice and VERY useful to be able to delete photos marked as Rejected (X), EVEN IF they are stacked in pills. In order to delete all rejected photos , I first need to unstack all pills, which is very time consuming.
'Pills'? I assume you mean 'stacks'. A stack is always limited to where you made it, so if you stack images in their folder, they won't be stacked in some collection and vice versa. So there is a good chance that these images are not stacked when you select 'All Photographs' all the way at the top left.
By the Way: There is a menu 'Expand All Stacks'. That should do it too.
