The drag-to-open function is useful, but the sensitivity is too high. Thus, it often opens anchors from notes in a new column instead of recycling the open note column, which is disruptive.
The drag-to-open function should thus either be less sensitive (and not activate after only a few pixels), or be able to be set by the user.
(For examples of this disruptive behavior, please see this thread where on May 2 screenshots of the problematic grab function are included, and this poll regarding lack of note functionality which requires the user to constantly open anchors.)
Thank you for considering this.
