Add ability to link effect values across separate clips
Have you ever run into a situation where you want the ability to adjust an effect across multiple clips automatically without having to copy and paste them manually? I run into this problem all the time and the workarounds I've come up with (a whole lotta nesting) aren't the fastest nor best solutions. I would propose that this linking (which is really just linking the numeric values) work in a very simple and easy to understand manner such as this:
case 1: you have a serious of 15 clips that you want to apply a brightness and contrast effect to and you know you will want to change them all together but occasionally individually. You select the 15 clips and draf the effect onto the clips, isntead of simply applying the effect it also creates a link and turns on a chain icon next to the effect's name. Now when you want to change them you simply select the clips and begin changing them in link, if you want to change one on it's own you simply select said clip and linked effect and click the chain icon which unlinks the effect until re-engaged.
This is a very interesting idea, but for the proposed use case adjustment layers would do the trick.
