The current method of opening multiple folders into one contact sheet is slow and awkward. I keep my images in a hierarchical folder structure. To open all the images in all the folders contained within a parent folder I must double click the first child folder and then control click each of the other child folders.
Could we have a single command to open a folder and all its subfolders?
I plan to have a solution for that at some point. It is potentially a very long operation. For instance if you told PM to open all subfolders of a given folder, there could literally be hundreds of thousands of images all totaled in all of those subfolders. This would not be a good thing.
So in order to do this I need to have a progress dialog to allow you to break out of the scanning process. Due to the way the scanning code operates on the main thread of the application, this is not a trivial change to make.
