Slow motion fit/stretch to fill
When applying a speed change to a clip, it would be most helpful to have premiere know how long it needs to make the clip in order to butt up to the next clip on the timeline.
Currently you need to measure the duration you want the clip to be before you go into the speed adjustment and then enter in the duration.
Or preview the clip on the timeline while adjusting the duration.
Also, have checkbox NOT to overwrite next clip on the layer.

Allan that is quite good! Thanks! I have been using PP since 3.1 and that little nugget has eluded me.

If I understand you correctly, the easiest way to do this is with the rate stretch tool (R). You just drag the clip out and it adjusts the speed until it is long enough to fill the desired duration.
