Dropshare 5.30 and newer
If you want to configure upload preferences (URL shortener, filename randomization and appended integrity hashes) per connection you can do so from the connection preferences.
Open the Dropshare Preferences from the menu bar icon, navigate to Connections and click the menu button for the connection of your choice.
Click on Upload preferences… and configure the overrides for the default preferences.
In order to reset the overridden preferences and have the connection use the global preferences again, click Reset.
