Quickly send files, paste images/text snippets between devices.
I'm using the older Snapdrop (which PD was forked from) with some patches I made to:
- Work behind Authelia for SSO + 2FA
- Use the display name provided by Authelia instead of the random usernames it gives out by default
- Send transfers over the internet without dealing with the temporary "rooms" that Pairdrop uses (it's behind Authelia, so only authorized users can get to it).
It has 100% replaced emailing things to myself or shuffling files to/from Nextcloud. I probably use it to send text (URLs, clipboard contents, etc) to/from my phone as much as I use it for sending files back and forth.
