I've written an Bittorrent Sync indicator for Linux Desktops (specifically Ubuntu, but may work on others too - let me know!). It basically displays the same information as the WebUI - which folders are syncing, and which peers they're syncing with. It has an animated icon to show when something is syncing, and there's a function to copy secrets to the clipboard. You can get it, find out how to use it, and report bugs at https://github.com/marxjohnson/btsyncindicator. Enjoy!
