* Give QMenu cursor: pointer * Darken border colors in dark theme * Refactor cursor: pointer event filter * Add QMenu stylesheet * Remove min-width for QMenu item * Add QMenuBar styles with increased height for touchscreen users and more visible highlight color. * Fix type * Revert "Add QMenuBar styles" This reverts commit 6ae405a073b15389b7926ef8aa91c3b228a7889e. * Remove strong border from QMenu checkbox style * Keep highlight color consistent * Adjust highlight-bg * Increase horizontal padding and adjust checkbox margin * Introduce border-faint var and make default border brighter in dark mode * Fix 1px move on hover and make highlight color more subtle * Remove win10 styles because the properties are set in the other stylesheets anyway. * Fix bottom border of QMenuBar not showing underneath entries * Remove unused import * Make border-faint one shade darker in light theme
