In the RB Notation window, there is a "peg" region (for lack of a better name) immediately below the buttons and above the chords.

This region displays the current playback/record cursor that is in in sync with the other timeline views of the project.

It can also be clicked in to change the playback cursor (e.g. for a paste function, to begin playback at that point, etc.).

The size of this region seems a bit narrow to navigate with a mouse (e.g. on higher res screens). Currently, if you miss this region too "high", you can accidentally click buttons or open the track drop-down list box (yes, I've done it plenty). If you miss this region too "low", you can accidentally insert a verrrrry high note (yes, I've done it plenty).

It would be useful if this region were taller.

- or - even better -

It would be useful if you could click anywhere above the chords to have the same effect as clicking in the "peg" region.
