I realize that we are not on the same line
- I don't have any problem concerning cutting bin clips or sequence clips.
Before asking a question, I always try as much as possible, to find if it has already been answered. I always read the guides or helps.
My question was specifically targetted to effects. I find confusing to apply effects to the bin clip, then apply new effets on the sequence. It may make sense (specially for Color Correction) to apply some to the bin clip, then apply other type of effects (i.g Motion & Transforms, Blending) to the sequence clip.
In order to check what is appening, I made a test :
- on clip bin = effect temperature (-11.00)
- on sequence = I added a zoom effect (the previous effect temperature is listed), then I modified the temperature value.
If I go back to the bin clip I only have the effect temperature to the value set to -11, which is great, but the title of the effect windows don't show if we are looking at a bin clip or a sequence clip, nor that the bin clip as already been used. This may lead (in a real project) to errors and incertainty - you may have forgotten that the clip as already been used on the timeline.
Continuing my tests, I noticed that once on the sequence line, a modification of the bin clip when there is no modification on the sequence clip, is not propagated... I was expecting exactly the contrary !!! Thus my questions 
For all these reasons, there should be a clear indication (on the bin list may be), that a clip as been used (once or more) on a sequence, same on the effect screen (bin - bin already used - sequence clip).
Concerning these topics, I don't see anything in the documentation...
A great feature would be to have a printed report of the "montage". It would help reviewing the "cuts" after production.
As well, it could be usefull to be able to cleanup the project from the unused clips before backup.
Thanks for your replies and sorry for the confusion I created with my initial question.
