Change length of transition by moving the 2nd video clip

I agree. I made a very similar suggestion before:

That’s not what Cut in transition does. Cut in transition is actually a useful option if you are putting different clips together but the audio is not playing right with those clips side by side like producing a pop or crackle sound. By creating a transition clip and picking Cut then it would play the video as if it was just a regular cut but allow the audio to be mixed in well and hopefully avoid those pops and crackles.
