Acer, you can collapse the right rail while in source mode - click the vertical strip just to the left of the rail.

I understand that it is not your preferred edit style, and that's fair - however this style means the save button is always on screen, and works for many 'orders' of editing. In the end, it's not a big change: you just move your mouse to a different location. In terms of keyboard interaction, it should be identical.
