I'm using WeBuilder 2020, latest version. That version has Chrome 70 as Preview engine, while Chrome's current version is 91. I'd like WeBuilder updates every 5 whole-point versions. With Edge and Opera having switched to the Chromium engine, Microsoft is actively discouraging the use of Internet Explorer, and Safari and Firefox generally keeping up with Chrome's ever advancing feature support, we can now use those new features. But with WeBuilder's Preview engine running behind so far, that's very difficult.
(For the rest, I think that WeBuilder is by far the best code editor. If its revenue is not what you would like it to be, it's due to your marketing. The product itself is fantastic.)
