Microsoft has made available in various places a list of the features it is building, considering, and back-burnering (is that a word?) for its Edge browser. But as of this week, there's now a new "What's Next" page for Chromium-based Edge that makes these features easier to see and track.
Microsoft already offered a roadmap for some of the enterprise features in the new Edge as part of the Microsoft 365 roadmap. But the "What's Next" page on the Edge Insider roadmap will offer a more complete roadmap, bringing together a list of some of the planned consumer and business-focused features. (I say "some" here because -- like all Microsoft public roadmaps -- not every feature gets listed. There are almost always surprises, both good and not-so-good.)
The What's Next page is good, but not perfect. I'd like to see the features called out listed sequentially -- either by date or browser version number. I don't think there's any rhyme or reason as to how they're listed at this point.
Another potential improvement: More detail on exactly how a feature is being made available. For example: Vertical Tabs is listed as a feature of Edge 88. The entry doesn't mention the way a user would have to enable this is using edge:/flags because Vertical Tabs is still considered "experimental." I think this level of granularity would be helpful for mainstream users.
