@[email protected] dunno, I'm just writing what I see. Before, I assumed that their conflict resolution is by merging the .md altogether with the most recent updates from all synced devices, but that doesn't really make sense in technical level. I think what they actually offer is control for syncthing via Obsidian's menu, rather than using Syncthing's interface.

@[email protected] reading the readme (https://github.com/LBF38/obsidian-syncthing-integration - or search Syncthing Integration on Community Plugins), it apparently offers conflicting files resolution (happens to me from time to time when I forgot to sync before opening daily notes, but not a big deal) and an option to modify .stignore from obsidian (stil in beta, and also the same for most of the configurable settings), among other features. Just to be clear, you still need to install Syncthing on your devices. I'm not in the position to give any meaningful review for them, though.

@[email protected] Syncthing worked wonders for me, though it is only recently that I knew about Syncthing plugin on Obsidian; I used syncthing without it. I used it to sync notes for three separate vaults between my laptop and android phone.
