P: When selecting a collapsed stack, provide option to apply changes to all photos in the stack

Well said.  My problem exactly.

There are two imperfect workarounds:

- Before making the change (e.g. applying a keyword), shift-click the stack-count badge in the upper-left corner of the thumbnail. That will expand the stack and select all the photos in it.

- Use the Syncomatic plugin.

I got enormous amounts of images in my daily folders. The amount clutters the view so I'd like to be able to stack before I apply keywords. But then only the top image is tagged.

Please add a preference to treat changes to a stacked top image to cascade to the rest of the stack's images. I stack dozens of bracketed shots when scrubbing and cannot stand having to expand the set to apply keywords, delete the stack, etc. I realize people use stacks in various ways, but I use them mostly for bracketed shots and pano sets when every shot within the stack is essentially considered 1 'shot' for my purposes. I want to be able to treat a stack as a group--even when the stack remains collapsed--when working with it. For example, delete the entire stack (bracketed or pano shots), apply the same keyword(s) to every image in a stack, or move the entire stack (to a diff file location) when the action is performed on the top-most image in the stack. This would GREATLY improve workflow efficiency when people use stacks for sets intended to be output to a single image (HDR, pano, etc). Perhaps a preference of how to handle stacked images (i.e. Stacks: Cascade all non-develop changes and operations to all images in the stack--deleting, moving, keywording, rating, etc). But having hundreds of stacks and then having to expand them individually to do basic operations just considerably limits the usefulness of stacks. And as someone who may have 100's of single images as well as 100 bracketed sets of 5-7 images each tends to make me want to pull my hair out during basic workflow operations.

It goes against my principles to go and pay for something to add a function as mundane as what's being requested here. Even if the plugin were free, it makes total sense to have this function in LR natively.

I too wish this were available in LR. Meanwhile, check out the Syncomatic plugin, which gets the job done.

Agreed. This is still not added in Lightroom 6.4, which is sad, because it shouldn't be too difficult to build in.

I always find myself going through my folders after culling&rating, finding stacks and re-applying flags/keywords/ratings/labels to pictures inside the stack, copying them from the topmost picture. It's cumbersome, time consuming, and from what I know an easy problem to solve without adding (much) overhead to either the program or other users.

When images are stacked, and the stack is collapsed; Provide a way to apply metadata changes to the enitire stack without having to expand the stack. Let's say I want to add a keyword to 3 stacked images. As it is now I need to expand the stack, then highlight all images in the stack (click on first, then shift-click on the last), then make the keyword change I want (say click the check box on a Keyword in the Keyword list) which will apply the change to the selected images. Now, I need to re-collapse the stack.

What I'd like to do is highlight image(s), some of which may be top of collapsed stacks, then in some way tell LR if I want my next change to apply to just the selected images or to the selected images and all images under them in collapsed stacks. Perhaps a toggle somewhere that affects this behaviour.

reject photos, stack them, collapse the stack & delete rejected photos. Rejected photos in the stack aren't removed.

When I select a collapsed stack of photos and enter some keywords, these kewords are only applied to the top (visible) picture. Seems as if only the top picture is selected, not the whole stack underneath.
The same behaviour can be observed when selecting the collapsed stack and convert to dng. Only the top picture gets converted.

Is this intended behaviour?
I think it's a bit awkward to first expand the stack, do something and then collapse it again...
