I am used to add fades and fade to blacks directly on the timeline. 
Just recently I am noticing that if I have a transition over a video clip, clicking on the video clip does not pop it over the transition so that I can drag in the fade from black effect. 
I do remember another bug where someone requested this sort of behavior, but there may still be room for improvement in the implementation. 

Clicking on a clip in the timeline should pop it to the foreground so that one can add fades.
Also, clicking on a clip should also pop forward any transitions that are between that clip and a clip on the track below. This will obscure the bottom corners of the active clip, but since there are no shortcuts on there, it should be OK. 
I do believe that this requested behaviour would be the best fit in all cases. 

Reproducible: Always

Steps to Reproduce:
1. Add a color clip to the timeline, and shorten to 3 seconds.
2. Add a video clip to the timeline, and stick it right next to the color clip.
3. Create and add a title clip, five seconds in length, to the track above the track with the color and video clips.
4. Add a fade from black to the video clip on the timeline.  

Actual Results:  
Clicking on the video clip does not pop up the clip over the transition. 

Expected Results:  
Clicking on the video clip to pop the video clip over the transition so that it's possible to drag in the fade from black.
