I’ve noticed two new behaviors in 3.7.3. One I like, one I don’t.
Previously, if I pasted some audio from the clipboard to the very beginning of a track/clip, the entire clip would slide to the right. I would then have to grab the clip and slide it back to the left detent. In 3.7.3, that behavior is gone.
Previously, if I pasted some audio from the clipboard to the very end of a track/clip it would just expand or reduce the clip end to fit the paste. In 3.7.3, a new clip is created, abutted to the end of the original clip. Now I have to join the clips.
The first behavior is fine, the second behavior is a pain but easily handled.
