Columns widgets have some customization options. You can change the order of columns, choose which columns to sort on, and also hide and display the columns you want.
Below you will see a clip from a widget with said columns. Holding the mouse pointer over the column head will result in an arrow pointing down to the right of the column head. Clicking on this will bring up the menu shown.
To change the order of a column, drag and drop by holding down the left must key.
Change the title of widgets
In widgets with dynamically translated titles, typically for widgets that can show a great deal of variety, the title can sometimes be confusing, or sometimes too long.
You can override these titles by going to "Advanced" - "Change widget titles". You then get a window where you can override the titles by double-clicking in the "Override" column and entering the desired title. Any overridden titles will also be included in any page sharing.
NOTE: For overwritten titles, there is a risk of confusion if you change the selection. In the case above, the widget on the right will not change the title even if you change it to show sellers instead of customers.
Faster access to widget menu
The menu available when left-clicking on the gear in the upper-right corner of the widget's header is also accessible by right-clicking anywhere on the header.
Browse the pages quickly
By right-clicking on the page icon in the upper-left corner of the dashboard, you will get a menu that allows you to switch to the page you want.
