Russ,

Got your point. The meaning of this variable should be "enabled or disabled". It is used to prevent FF/RWD at paused state. IMHO, the global `isPlaying function` or `isPlaying variable` are similar to each other. So, I would suggest to rename the variable name or change it as `setEnabled(boolean)` because of its meaning.

BTW, if UX accepts to enable the FF/RWD at the paused mode, we don't need this variable or global dependency anymore. Thanks for this.
