You can customize a widget by configuring it or personalizing it.
Other users see the widget at its original height.
There is a hierarchy to customization. The changes that you make when personalizing a widget override any changes that an editor has made when configuring it. For example, you edit the settings for a widget that refreshes its content every 60 seconds. If you then personalize the widget to refresh every 30 seconds, the widget refreshes every 30 seconds for you.
The values you set when personalizing a widget continue to override the widget settings even when an editor subsequently changes the widget settings. That is, the widget continues to refresh every 30 seconds even if an editor changes the widget to refresh every 40 seconds. The widget might provide a Reset button to cancel your personalizations and return the settings to the values set when an editor last configured the widget.
