Show automation enevelope level changes in real time.

If I turn on the volume envelope, the level of the envelope line will be at the level of the actual volume fader. If I move than the fader, the volume envelope line will not change and will stay at the initial level, until I turn off and than back on the volume envelope. It does the same even when I turn on the envelope offset mode. Wouldn't be nice to show the buttons and faders level tweaks in real time on their envelopes like in Ableton Live ?
