If you already have the Opera web browser, you may also have widgets (if you don't, try downloading some--see Related Articles). But if you want to reopen a widget, or delete one you'll need to 'Manage' your widgets...
Remember; if you delete a widget, you can always redownload it.
Another way to open widgets is to select the Widgets dropdown menu and click on the widget of your choice there.
Most widgets have some form of 'off' button on them, be it a little 'X' in the corner or an 'Off' button. You can use these functions instead of the Management tab.
Step1
Open Opera up. It does not matter what window you're at; you can Manage your widgets from any Opera window.
Step2
The Dropdown Menu
On the toolbar at the top of the window, select 'Widgets', then 'Manage Widgets'.
Step3
Widgets Management Page
A new 'Widgets' tab will open. Select a widget on the list below it.
Step4
Open or Delete
Select 'Open' or 'Delete'.
Step5
If you select 'Delete', the widget will go away forever, unless you redownload it later. If you select 'Open', your widget will open...Yay!
Step6
Close
If, once you've opened a widget, you'd like to close it, go to the Widgets tab, highlight the opened image and select 'Close'.
