It would be great to have the option to zoom in/out by simply dragging the scrollbars in the Project window. This would make zooming more intuitive and fluid, especially for users coming from other software 
The Project Window already has scroll bars for zooming.
What other software has zooming using the scroll bars? None of mine does.
In Ableton Live, you can zoom in/out by directly dragging the scrollbars in the arrangement view, and it feels much smoother and more intuitive for my workflow.
Oh well, I just press “G” or “H”.
WaveLab, Reaper, Ableton Live. FL Studio even shows the playback position in the horizontal scroll bar.
