[DEPRECATED]
Today marks the release of the somewhat overdue update for syno-indicator, the app indicator to keep an eye on the download station of your Synology NAS. The 0.5 release mainly contains bug fixes and compatibility improvements with later versions of Ubuntu, but also features immediate updates and some handy status icons for every download.
» Download
» Project on sourceforge
Tested on DSM 5.x with Unity, MATE and GNOME 3
PS: GNOME 3 users may want to install the topicons extension as well.
