Q: How to make Trackpad three finger "drag and drop" quicker?

How much of a delay are you experiencing?

Is this a recent development?

What kind of detail are you trying to drag and drop, when one finger 'highlight, hold and drag' seems sufficient.

For the record, my drag and drop is virtually instant.

I have to say, I fail to see any connection between your link and the question.   If anything it is quite unfair to people who offer help in the forums to have to waste their time with matters like this.   I am reporting the post as such.
