Opera Unite and widgets phased out
The little-used features Opera Unite and widgets have been deactivated by default in Opera 12. Unite actually was innovative: It let you set up your computer to function as a server through Opera. Unite was promoted prominently as a main attraction for using Opera when it was first introduced, but for some reason it never caught on with users. Widgets are being phased out in part to remove users’ confusion with extensions, and developers of Opera widgets are being encouraged to write extensions instead. The code for these two lays dormant in Opera 12, but will be removed from upcoming versions of the browser.
