It’s possible to add multiple links to a file or folder (Share link / Add another link).
However, the activity notification does only say “{file} downloaded via public link”.
Please extend it to something like “{file} downloaded via public link {share-link}”.
What is the purpose of multiple share links, when you never know which one was used?
I have tried to patch the sources for my installation, but due to my little experience I did not find the right place for the enhancement.
These are the places where I was trying to implement my desired feature:
/var/www/nextcloud/apps/files_sharing/lib/Activity/Providers/Base.php
/var/www/nextcloud/apps/files_sharing/lib/Activity/Providers/Downloads.php
/var/www/nextcloud/apps/files_sharing/l10n/
If somebody has implemented this feature or can tell me how to implement it, please share your information.
If you want to see a new feature implemented in Nextcloud, I would recomment to create a feature request issue ticket in the relevant Github repository
