P: Custom sort order of keywords (instead of alphabetic).

The inconsistency of the requirements for uploading photos to your stock service with the capabilities of the main product for cataloging and tagging photos, which has not been fixed for such a long time - IMHO, is extremely incorrect and disrespectful towards contributors. Adobe, maybe it makes sense tho to take care of your contributors in this issue finally?

P.S.: The very fact that this issue is being delayed for so long and that there are no clear answers from the company is even more discouraging than the need to do additional work to rearrange keywords each time.

This is a very annoying problem for me too, just had a big rant on it here...

Before i was pointed to this thread. 

Its still ridiculous (and yes, the keywords are written in alphabetical order by lightroom) this is present.
Current workflow now involves exporting from lightroom then having to load bridge, select the newly exported photos, go to "File Info" and then cut and paste the same keywords BACK into the keywork field there to get them written in priority order.
Its a ridiculous extra step in the workflow for every image to upload to *their own* stock site!
And yes, its made even crazier by the fact they wrote a plugin for AdobeStock to upload but its unusable as it uploads keywords in alphabetical order!

Also interesting to notice this is a Adobe’s forum and does’t have any official response to customers needs. Let’s hope any new Ai technology can solve this issue!

yes. The funny thing is, Adobe Stock needs custom sort order and you have also a LR-Plugin for uploading your photos to Adobe Stock, but you can't use it - only if you like to manually reorder every single keyword in every single photo on Adobe Stock you could use LR and it's plugin. Funny or not? And if you do so, the status of your keywords in LR is a different one to the status on Adobe Stock.

The Adobe solution to its clients is to use another software?

@lumigraphics I think you don't understand what the issue is. The subject is, how to use LR for the work and not a different software. If you paste keywords into LR, LR will sort them and in the moment where you save your work LR will overwrite the keywords in the file. There is no way around this. Your solution is just, use a different software.... That is what all we are doing who needs keywords in a custom sort order.

Almost every comment here shows a fundamental misunderstanding of how keywords work. They are written to the file in the order entered. Its up to the client (program reading the image) to sort, or not.

If you want them written in a particular order, you have to delete ALL keywords from all four keyword namespaces and then enter them again, using an editor that writes in the order entered. THEN you need a client that reads them in order from the image file and doesn't reorder them alphabetically.

Photoshop DOES suppport a relevancy keyword order (meaning: the keywords stay in the order you entered them), only Lightroom does not.

I would prefer also a relevant order for keywords in lightroom and photoshop
