On the surface, this feature appears to be a valuable addition, and it aligns with Microsoft’s ongoing efforts to eliminate bloat and superfluous elements from Edge. Conducting a periodic sidebar cleanup, by highlighting less frequently used apps, is akin to a digital spring cleaning task that many users will find helpful.
It’s worth noting that Microsoft seems committed to applying the same decluttering principles to its own apps. In the test build of Edge, Skype is one of the suggested icons that could be removed.
