Bigger Keyboard´s Window reduce the visible octaves

Hi all

In Synfire all the File-New- windows :The Palette; Arrangement;Progreession;Sketch....have the capacity to zoom In - Out in height and width to fill the screen and this is great but with the keyboard window is posibble to fill  the screen in height but in width (i think is more important to see more notes) is limited  to show 16 notes,is not possible to fill the screen in width way wasting valuable space

You can see the gif video,open it with safari or Firefox

Is there any way to avoid this?

Oh;I have discovered now that if the keyboard window is in low high is possible to see more octaves and if is in high high the octaves reduce considerably

It´s a shame to lose octaves when is in big size if you have a big screen to widen the keyboard

Regards
