+### Note about caching
 
 When navigating to a new page, the old page is cached in memory. If you navigate back, the cached copy of the page is restored. Think of it as rewinding time — you return to a past time as if nothing had happened. The same applies to forward navigation; cached pages are loaded if available. This allows back and forward navigation to happen instantly, without any network requests.

+* Line width: This setting determines the maximum width for text lines. "Window" disables the maximum limit and fits text lines to the full width of the window. Shorter lines are generally easier to read.
