Hide Column in Xsheet Function Display

(1) I would like to request that in the Xsheet, the middle frame that displays the functions should allow Hide Column.
I have a deformer on an arm and I am only rotating the arm. So in the display I only need Bone Orientation
where I can see where the keys are set.

(2) Keep the Left Drawing GUI-Frame visually synced frame-by-frame with the Function GUI-Frame by adding in the same column header space
as the Thumbnails. Refer my attached .png for this to be clear.
