[IDEA] "Only when idle" option on instant play

[the_bertrum]

Would it be possible to add a function that allows the "Instant play action" to be only effective if nothing is currently playing?  This would stop me from frequently starting payback of another album due to a stray tap while scrolling.  I think from a UI point of view it could be a check box for "instant play only when idle" to turn it on, and then perhaps a drop down to select either "no action" or "add" for what the action should be when playing.
