The three views are:
- Classic - this is the default tree-based view as shown in figure Figure 1.
In default view, built-in tabs are displayed in the sequence "Properties, methods, events," and the tabs that are specific to custom view are added at the end.
In case, Classic view option is selected, the sequence of tabs for component XYZ will be: Properties|Methods|Events|Device Settings.
- Custom - when the Custom view is selected, it is marked as replacement of built-in tabs and replaces their position with the built-in tab.
In case, Custom view option is selected, the sequence of tabs for component XYZ will be: Device Settings|Methods|Events|Properties.
- Tabs - this view displays configuration elements in graphical form, better organized, easy to understand and use. Nested tabs and tables are used to present complex configurations as shown in figure below.
Note: After selecting the required view, restart or switch the workspace to display the selected view in Component Inspector.

In the Preferences dialog, you can also choose the number of columns that will appear in Component Inspector view for displaying properties.
Select Inspector columns count and choose the value from 1 to 4 from the drop-down list. This option is valid only for Tabs view.
You can filter pin names in the Component Inspector view. It is now easy to select pin from the long drop-down list. You can type the text and filter list of available values. Filtering is enabled only when more than 3 values are available in the list.
