Clip mobility in the time line and precision trimming ability

I am a great fan of Audacity. I love to see two main changes in audacity. I believe this is going to be a game changer.
1- An easy way to cut/trim clips precisely. (Avoiding copy and paste concept).
2 Ability to freely move clips around in the timeline. Currently clips stick to the track and is not movable, Moving clips helps to match the beat precisely the clip in other tracks.
