The slide in LEFT menu feature implemented in AwareIM is focused on MOBILE use rather than using it in the desktop.
Currently it supports only single menu items. If I have a hierarchy in my menu and click on the expand menu option, it closes the menu before I can select the menu item. A Standard menu with a hierarchy is not supported either.
Also, the auto collapse feature makes the menu totally disappear, having the option to semi-collapse to the Menu icons only would be good for better menu behavior and be more user-friendly.
I asked support if they would consider extending the functionality of the Drawer widget to include the above functionality.
They responded: Its already been done and will be in the new release 😃 😃 😃 😃 😃 😃 😃
Here is a link to the Drawer widget in action - collapsing to icons only will make my menu system rock (click on the main menu hamburger icon to see its action)
