Requested feature
It would be great if the 'Edit' menu had an option to select all jpeg photos, or more generally, all photos of a specific type (similar to being able to select all photos with a given colour code or a given rating).
My use case
I shoot raw and use PM to select and crop all my raw files. Once they are cropped, I select all cropped images (function available in the edit menu) and send them to 'PhotoShop/Camera Raw' for editing. I then save the photos as jpeg which is the format to transmit to my clients in the same directory as the raw files. I then select select all jpeg photos in PM and caption them. Currently to select all jpeg files, I sort them using the {type} tag. While this works, the photos are no longer respecting any other ordering, especially 'Creation Date'. This makes it sometimes hard to caption photos (e.g., in track and field if editing multiple races, it becomes often unclear in what race a given competitor was competing without explicitly considering the timestamp). This is cumbersome especially if using copy/paste of captions from the previous photo (and only changing the athlete's name).
Workaround
Alternatively, I could save the jpeg files into a dedicated sub-folder and then have all functionality needed in that sub-folder (but I like to have all photos, raw and edited, in the same directory).
Another workaround would be to display only selected photos (using the option available) and then sort using 'Creation Date'. The issue with that workaround is that as soon as a image gets unselected (for example when first considering starred images for captioning), the approach falls apart.
There are probably other use-cases where the workarounds do not work or do not make sense.
Note
This feature was requested in 2009, but has never made it to implementation.
