Parameter or button or media rule for "forcing" mobile view in portrait-orientation on hd-displays

[patrick-77]

Is your feature request related to a problem? Please describe. Yes, sidebar is not hiding and style won't change to mobile view on portrait-orientation on windows-devices with hd-resolution (perhaps in other desktop-os's too). A wall-mounted display in portrait-orientation and a windows-tablet in portrait-orientation won't activate the mobile-view until you increase zoom to 150% (chrome)

Describe the solution you'd like Additional Parameters or a combination like

• extend media-rules with breakpoints depending on orientation
• button for switching from mobile-view to "desktop-view" linke in chrome devel-tools
• $conf['tpl']['bootstrap3']['hideSidebarOnPortrait'] = 1;
• $conf['tpl']['bootstrap3']['mobileViewOnPortrait'] = 1;

Describe alternatives you've considered View can be switched to mobile-view by

• Working in a browser-window with reduced width
• Scaling to 150% of Zoom
