Another thing I never use is the Demo Play button as you always use the style preview play button in the style picker, you don't pick a style, close the style picker window go back to the VST and hit Demo to listen to it, then if it don't sound suitable you go back in the style picker pick another and do the same.......
If you add the Sync Host button there then you just click it if you don't want the tracks in the VST playing back with the host, if you want them to play back with the host you click it again, how it is now it plays back with the host if you like it or not.
