I had already posted this feature request in January:
Traslation:
I myself would like this bar for the editors (especially MIDI and drum editors). The docked editors of the lower zone are too small for me on the laptop, so I prefer to use the old editors in full-screen mode. In this case, however, the transport bar in the project window is no longer useful.
Additional note: The F2 transport bar is not a solution for me because it always hides something important in the full-screen-editor window.
