Please just open the photo. Not helpful to just say: previously added
Please change Lightroom CC so that it simply opens the photo if it's been through Lightroom previously.
Fantastic that you developers use only the Lightroom library to navigate your photo history. Many other users have their own project-based filesystems in native operating systems like Windows.
Many other Lightroom users ... you know, your PAID SUBSCRIBERS ... simply double-click to open a file. It's a fundamental expectation of computers that double-click opens a default application. For example, Lightroom as default editor of photos.
If you double click a photo you've previously edited, then all Lightroom will do is say: Previously Added. Which is NOT HELPFUL. Just open the file.
Why would a user re-edit a file? To crop differently. To mix the color and light different to request. These are routine tasks.
When Lightroom says only Previous Added, now the user has to navigate the Lightroom Library. What day was this photo edited? Dunno off hand, have to research. Okay, found the date. And there's HUNDREDS of other other photos now to paw through on that date in the Lightroom Library.
It's a frigging waste of user time to research and search the Lightroom Library.
JUST OPEN THE FILE!
Lightroom knows where the file is in its Library. JUST OPEN THE FILE!'
Thank you.
