Switching between touch and classic view in AEM

Adobe has introduced a touch-optimized UI with responsive design for the author environment & is default one. Based on project deliver & timing till all authors get trained you might want to make classic ui has default one. Below are the two steps to do in AEM 6 .

For landing page configure the rootmapping.target as welcome from projects.html at http://<host>:<port>/system/console/configMgr/com.day.cq.commons.servlets.RootMappingServlet


There are two options global level & user level. I would recommend User level because there might some authors already trained on Touch UI & some authors like to play with both till they get used to new UI.
To change at user level there is an option to toggle authoring mode Touch UI vs Classic in User Preferences modal. You can open it by clicking the user icon in the top right hand corner and then clicking the gear. Screenshot below

Other option is to Change UI mode to classic at global level by changing the property authoringUIModeService.default from TOUCH to CLASSIC at http://host:port/system/console/configMgr/com.day.cq.wcm.core.impl.AuthoringUIModeServiceImpl

Note: Changing at global level makes not to edit in touch ui even from touch ui console & author has to remember the url if they want to use touch ui.
