Linux is still missing something which had as tight a development loop as VB in terms of "intent -> result" (I've never managed to get Glade or any of the similar GUI tools working, and thus never really written a GUI app in Linux).

Or Lazarus, for the Delphi variant,
People hate changes, even the slightest UI color changes are booed down. I can imagine redoing Lazarus to look like IntelliJ IDEA would be a lot of work that would be frowned upon (though I love IDEA... but I myself find it not tempting at all to switch to their "new UI" which copies VS Code and hides away my most frequently used features behind submenus and pictures, like I can't read ;-) (old man yelling at clouds)).
Workspaces as a way to have the concept of Smalltalk images, while being based in files.
To this day it supports code navigation like in Smalltalk.
Ironically, VSCode was also created by one of Visual Age and Eclipse architects, Erich Gamma.
My advice to developers that are interested in Xojo, or looking for something different in terms of languages / development platforms, is to give Xojo a try. You can build and run apps in debug mode for as long as you'd like, all at no charge. It's only when you want to compile apps so that you can run them as executables and/or for distribution that you'll need to purchase a license.
