Will be very fine if you can add the following feature:
- cursor on chart in 'arrow mode', we can scale or drag the chart.
- double click on chart anywhere (other than chart objects)
automatically switch to the crosshair mode, the measurement tool where we can measure pips and bars.
- and viceversa
This will help and save time avoiding to click the button 'Set Cursor Pointer' a lot of times.
It is a more convenient and usefull way to use the charts especially if we use 2 or more charts at once.

It is already done by pressing a middle mouse button.
