Copying this over from the German forum as I still think this is very valid:
Sometimes, I want to work with clients who should not need to worry about Seafile. I give them an upload link to share files and also a corresponding download link so that they can get files I put in that folder. So they can add files, download files but not remove files.
It’s cumbersome, though, and hard to explain why they need two links.
I propose to allow download in the share dialog and add that functionality to the upload links (when download was checked).
This would be a huge usability improvement and maybe a low-hanging fruit to implement.
