Opera Software has announced that they are going to focus on support for browser extensions in the future builds.
They are going to discontinue the Unite platform and Widgets in the coming months.
Starting with the upcoming Opera 12 release, Opera Unite and Opera Widgets will be turned off by default for new users. The two Add-on platforms will be completely removed in a later release expected before the end of this year.
Moving forward we want to focus on one high quality Add-on platform across our products, rather than spending resources on maintaining legacy systems.
Opera Widget platform enabled users to run small apps on their desktop without requiring the browser to be running in the background. Opera Unite came loaded with several powerful applications like a web server and a music streaming app.
