Option to change the width of the sidebar

In some of my projects, I have a lot of columns with large forms. Being able to change the size of the sidebar in a config file would be incredible awesome.

Sure, I'd merge a config option for this. Maybe we could use md, lg, xl (md as default) in the config.

Yeah but also be able to downscale the sidebar. As you see in my example, the sidebar is much wider than the content

Sure - an sm option too.
