The editor they shipped had some neat features for the time like Intelisense and built-in docs, it even had support for third-party libraries with DLLs. One really neat feature I also remember was that you could turn a SB project into VB with a click of a button, it would create the VS solution and vbproj for you. I'm not quite sure how it worked with the language itself cause VB looks quite a bit different and it wouldn't change your code (no transpiling or stuff like that, just a wrapper).
Funnily enough, I didn't actually move to VB from that, I went to C# (which I have since forgotten). But it definitely got me quite a bit further in my developer journey (now I work with Go at a small org).
