Syncthing

Advantages

• much faster than Nextcloud, once it gets going.

Disadvantages

• no way to access files in a share without downloading all of its files
• no central server (even as an option) for easy access when outside of the LAN

Needed Features

• a way to run it headlessly (maybe this is possible already, but not sure how)
• better share management across multiple clients -- any of the following would help:
  • a way for clients to designate shares as controllable by other machines (ideal, but more work to design/code)
  • import/export for the shares on any given client (should be an easy fix, would at least allow management via fingernet)
  • some indication of which client first created the share (helpful, but doesn't fully solve the problem)
• a "notes" field for each share, so you can document its purpose/usage
  • Ideally, there would be both public notes (which would be visible to remotes) and private notes (which wouldn't, and could be added to shares defined remotely).
• a way to include linked folders in the sync-set/share
• ability to connect to specific folders within a share, and attach them to whichever local folders I want
• ability to browse available shares without downloading them or setting them up
  • (This would also make it possible/easier to start setting up a share without having to wait for the invitation to arrive.)
  • ability to download/upload specific files without downloading the whole share
• notification when local disk is full
  • From what I can tell, syncking just stops when the disk is too full; sometimes the share's status even claims everything is fine, except files won't synck up or down.
• when a remote or share is "offline", some kind of explanation of why -- seems to be multiple possible reasons (including local disk full, which shouldn't be)
