LFO delay for instrument LFOs that delay the kick-in of the low freq osc smoothly so that it fades in the longer the more of delay is applied.
examples of use:
Vibrato effect
Tremolo effect
Pannings
Various effects
Would of course retrig for every noteon.
Some other suggestions regarding instrument LFOs that have already been suggested, but as a reminder for not to forget the pinned RNI future thread:
Multi/mono mode, multi affecting every note separately, single the whole output of an instrument.
Free/retrig mode for controlling if noteon restarts LFO cycle.
Amount/speed based on velocity. ( 
)
Single cycle switch?
