When Raindrop.io is available in the macOS share menu, it'll become easier to add different items to Raindrop.io.
I know there's the Safari extension, but that's just for web-links.
This appears to be now be possible via the expanded share, actions and shortcut options in iOS13, but not having upgraded to Catalina yet I can't confirm if possible there:
Latest Safari extension is have support for macOS Share menu. But only for links at the moment.
Support for files will be added in future
@Rustem Mussabekov: Thanks for adding this! I had the mac app downloaded but didn't know I had to also download the extension app from the app store as well. Right now the share menu popup is white, can you please add dark mode support Mojave/Catalina or option to change the color of the popup?
It would be very useful because Safari extension wants to login every time when I want to save link.
