While in a contact sheet, PM has always allowed you to select the sort order (Filename, Capture Time etc) then manually drag any rogue photos into the right order. After dragging the first image, you would see the sort order switch to Arrangement. Unfortunately it appears to no longer work in PM5... unless I'm missing something.
In the current version, while viewing a contact sheet sorted by Capture Time, I tried unsuccessfully to drag a few out-of-order images into the correct order. I switched to various other sort orders but none of them would allow any manual sorting. The only way I could do any manual rearranging was to start off by selecting Arrangement first, but then I would loose the Capture Time sort that I needed for 99% of the photos I was working with (switching to Arrangement appears to sort by filename).
Please tell me this is not by design... having the ability to choose a sort order first before tweaking the arrangement manually is what makes it such a great feature.
I'm using the latest build released today, 13057 (acc29f8). Thanks.
