This plugin moves the main navigation menu, header and user panel to the left sidebar.
The work was checked on the default style. From the settings for now, enable/disable side navigation and enable/disable navigation pinning at the top of the screen when scrolling. The color scheme is taken from the standard style settings, and is also customizable there. Options are made in the style settings, which will allow if there are several styles on or off. Side navigation for each style is individual.
