I love Vivaldi, the browser for power users—but these 4 flaws are wearing on me

Here is a 196-word summary of the key points from the news article: The article discusses the Vivaldi web browser, which is praised for its focus on power users and customization, but the author highlights several areas where Vivaldi falls short compared to other browsers. Firstly, the article criticizes Vivaldi's plan to stop supporting the popular uBlock Origin ad-blocker, instead relying on its own less effective built-in tools. The author argues this goes against Vivaldi's mission of empowering users. Secondly, the article notes that Vivaldi lacks the ability to sync a user's full browser setup, including features like Workspaces and Web Panels, across devices. This is seen as a major limitation for power users who use Vivaldi on multiple computers. The article also laments the lack of extension support in Vivaldi's mobile app, while rival browsers offer this functionality. Finally, the tablet app is criticized for lacking key desktop features, making it a "pale imitation" of the full Vivaldi experience. The author concludes by urging Vivaldi to focus on improving these areas rather than defining itself by what it doesn't do, in order to better serve its target audience of power users.
