Create a custom perspective using panels?

Hi Manpreet

A perspective is a predefined layout of panels in the Developer Console Log Inspector.
When you perform a task in the Log Inspector, use a perspective that makes completing the task fast and easy. Every developer has a different style. For a list of out-of-the box perspectives, see Log Inspector.

To create a custom perspective or modify an existing perspective:

1. In the Developer Console, open a log in the Log Inspector.
2. Click Debug | View Log Panels and select the panels you want to include in the perspective.

For a list of available panels, see Log Panels. If you modify a perspective, an * is appended to the perspective name until it is saved.

#If you create a perspective that includes the Execution Log panel, you may want to include the Source panel.#

To save your changes, click Save Perspective. To create a new perspective, click Save Perspective As and enter a new name.
