Do you think that a simple right click->move image(s) could have any value?
Perhaps, but here is where I am coming from: I have a giant folder labeled "Unorganized" on my desktop where I save all my images, to later sort and categorize into folders. In order to do this, I need to sort through literally thousands of thumbnails and select dozens or hundreds of images, all the time holding the control key. If I misclick or accidentally let go on control, everything gets deselected and I have to start over.
I have several friends in similar situations, and none of them can find any programs which make this any easier than Windows Explorer. My plan was to find an open-source photo organizer, and add a "simple selection" mode, where plainly clicking on a thumbnail adds it to/removes it from the existing selection. Though My Photo Index is by far the best open-source photo organizer I've found, without the ability to view only files in a specific folder and move them to another folder, we can't use it.
(I was actually able to add this simple-select ability to another program, JPO, but unfortunately it's waaaay too buggy to actually be used).
Now that you know where I'm coming from, you can see why we'd want the ability to view folders. However, I realize this would be a great undertaking, so even a "move to folder" would be appreciated.
Thanks for your consideration, and for all your hard work on this great (and free) app!
