Draft: Reimplement "Make HeaderBar resizeable"
This reverts and reimplements "Make HeaderBar resizeable" by using the Setting dialog instead of making it resizable. Reason:
- Make it more visible to the user (in the Setting dialog instead of requiring the user to randomly move the mouse into the control bar to discover the ability)
- Most people just want to show the header or completely hide it, resizing is not really needed.
Also add the current track's info into the control bar.
"Draft" to see if you like the idea or not.
