So you are using 1.11.11 there should be another release soon 1.11.14.
The Plugin is an open beta test where everyone gets a chance to give feedback on issues and suggested features this gives a greater diversity rather than the closed beta testing forum that has limited users.
Until the synced playback is implemented you would be better using the Standalone version as there is no real advantage using the Plugin how it is at the moment.
