I frequently change between one and two horizontal columns in SublimeText while editing source code. Similarly, I frequently hide/show the file browser on the left side of the window. I use keyboard commands to quickly cycle through various views, however, the size of the SublimeText window stays the same irrespective of what is on the screen.
Ideally, the width of the window would update to fit everything. The ruler size could be used to determine the overall width of the window. Otherwise, just remembering the size for various views would be incredibly helpful.
Maybe this is already possible and I’m just not aware of it? Otherwise, it would be a killer feature, for me at least.
