I really like the way how the summary view now works including the zoom capabilities. More than the way when it was introduced (can’t remember when…).
What I liked in the “first version” was the ability to jump instantly towards a specific point. For now especially vertical in projects with many tracks.
What do you think about an extra “Navigator Window” which you can access by an entry in the window menu? I imagine a window which contains the summary view version 1 without the zoom possibilities (it would be confusing), so only for instant jumps or moving.
