It would be really cool if we could define LFO functions (sine wave, saw tooth, square, ramp, etc) and use them to control parameters, basically like an automatic expression pedal (think old blood noise endeavours expression ramper: Old Blood Noise Endeavors — Old Blood Noise Endeavors Expression Ramper).
You would be able to assign a foot switch to start the LFO, stop it, 1 shot it, etc.
a single LFO could control multiple parameters at once (same as an expression pedal can).
This would be similar to the new volume tremolo in CorOs 3.3.0, but it would be able to control any parameter instead of just volume, e.g. delay time, wet effect mix, etc.
