Web Services is steadily transitioning AEM components to ensure compatibility with the new touch interface, TouchUI. Adobe has announced plans to sunset the Classic Interface, which includes the Sidekick.  In the AEM Version 4.1 Release, Web Editors will see changes to the names of components and component fields.

Please use this table as a reference:

Classic Interface Name TouchUI Name
Responsive Columns Columns
Inline Text Editor Text Editor
Image with Crop Image

*Responsive Columns will eventually be replaced with Layouting, which is specific to the TouchUI.
