 Once you have a file open, the sidebar lets you quickly access the most common features as sidebar panels and keeps them available while you work. These panels can be moved to the upper-left (1), upper-right (2), lower-left (3), lower-right (4), bottom-left (5), and bottom-right (6) panel regions.
 
- - 1-2: This section is where the majority of the primarily vertical panels reside. You can only have on larger item here at a time visible. The default behavior is for a click on another panel icon to hide the previous panel. However, this default can be overridden by using `[SHIFT]` click. If overridden, both the old panel and the new panel will be visible.

  - 3-4: This section is primarily for smaller panels where you may wish to toggle multiple on or off. Clicking a panel here will toggle its visibility without impacting other panels.

  - 5-6: Primarily for horizontal content, the bottom-most panel icon regions behave much like sections 1-2 except they are applied to two regions in the bottom of the window. Clicking a different icon in this region will switch to that panel, or hide that panel entirely if it is already selected.
