The Column Selector is a versatile tool in Indigo, used in virtually every screen that contains a grid.
To access this tool:
Click on the Toggle Grid Options button in the toolbar.
Click on the Column Selector icon.
The following window will pop up. Note that the columns displayed in the selection reflect the view you saw previously. In this case, we are in the Work Schedule Profiles view, so columns relevant to Work Schedule Profiles are displayed.
Columns can be checked and unchecked in the main area. Checking a column will display it in the main view, while unchecking a column will remove it. The options at the bottom can help you check columns quickly.
Once done, click Apply to effect your changes and keep the popup open. Clicking Save will apply your changes and exit to the main view. Cancel will cancel any changes made.
If you'd like to save this particular column format for this view, click on the Save State button in the toolbar.
