Hey there!
Just like my predecessor 2 and a half years ago (syncthing-bar) I created a small macOS statusbar application. As distinct from this version mine integrates with brew’s syncthing.
The application is able to control the syncthing daemon, as well as access syncthing’d folders and the WebUI.
Installation is easily possible via brew cask:
brew cask install jonashoechst/hoechst/syncthing-brewbar
Also check out the repo containing my messy code: (https://github.com/jonashoechst/Syncthing-BrewBar)
I’d be thankful for any feedback! Jonas.
