From 36f42081d0d3e6f401e18bf84f6796ca8f8bcfb5 Mon Sep 17 00:00:00 2001 From: LuXu Date: Thu, 4 Nov 2021 12:20:28 +0800 Subject: make width of navigation area configurable (#155) this allows users to configure navigation width from config.h. it also allows disabling the navigation function entirely by using a 0 width. one extra functionality this adds is being able to define an absolute width (in pixels) instead of just percentage via `NAV_IS_REL`.
