Lightroom Classic: Badge to indicate which photos have been exported

It is not possible to search for "exported" as a word in metadata, since it is not part of the actual file.

The closest thing is using the metadata "Develop -> " but as mentioned,  "Exported" is not an option. Only "Has adjustments" or "Cropped", etc.

It is a workaround, however, your first option would start taking up a lot of space, and require me to constantly check the folder and which filenames are allready there. At least when I usually don't export files to HDD, only send them directly with FTP  (If I ever need those files myself they are still there, ready to be exported at another time - saves space.)

Second option would not help much as it would only rename the exported file and not the original one. Leaving me again to create a collection of mirrors to double check.

I appreciate suggestions though. :) Don't wanna be negative, but I still want that option to tag dem natively.

There is of corse a "workaround" this way :
Before (/after/wile) exporting, select all concerned and sync
- Add Keywords to exported photos (Have for instance a set of 9 related codes)
- or fill-in (for instance) the metadata-field  "Name of the copy" with something like "Exported" and /or "printed" etc.

(Then, these images can be searched and also will automatically populate correspondingly created Smart-Collections.)

( I just tried a way using "Create Snapshot" see if it's naming could be searched but doesn't seem to be possible. (But to include "Create Snapshot" in a workflow as suggested above, that could add sense- and call them like "Exported +date".)

That leads to an extension of Your suggestion : Add  Badge also for  "PRINTED".

Even better maybe :
Every export, and every printing, 
should not only get an automatic badge (within searchable metadata),
but it should also : trigger auto-creation of snapshots
named  accordingly (such as  "Exported_Date_Time"  or  "Printed_Date_Time").

The main reason I could use a searchable smart collection variable as to exported by LR or not is so I can know which pictures I have already exported using one of my presets for certain publications more easily & not have to try and guess the original filename before I renamed them while importing them / renamed them as I exported them to meet the publisher's specifications.  Otherwise I am stuck searching massive shot collections in Develop mode peeking in the history tab to see if it shows "Exported" for each and every picture.  Slow with > 252793 photos so far.

It also could let me know if I backed a photo up to a specific location so that I would be more comfortable removing massive number of photos from my LR catalog if I knew the photos themselves were backed up on an external/network drive for instance.

Changes are noted in the release notes, and the thread is usually updated when it goes live. They don't often update the thread or comment before a feature is made available.

Could you give us an idea of why you need to know whether you've exported? That'll help your case. 

+1 for me on this topic.  I integrate a few different device and activities through my lightroom processing, do some grading, minor touchups, dump the keepers to a drop folder for eventual placement in their long term storage.  I'll tend to batch this activity up every couple of weeks - but it's easy to forget which stage and from which source I've already moved through the process.  Activity is a bit interrupt driven so it's easy to end up with a couple day latency between some steps.

I think that all depends on each photographers workflow. I create a new folder for each client/project, and then want to quickly see which photos I have processed when it comes time to cull the dead ones, or to export a different process on the same image for variety, or to merge them. I think a lot of photographers would get value out of this - at least as much as the "has adjustments" badge, because frankly, what images don't have adjustments :)
