Pharo snippets: Improved about running process
While running Pharo snippets, the only indicator is a grayed play and inspect icon instead of loading/running bars (as show in the screenshot below). For particularly long running process, like installations with a lot of dependencies, the user doesn't know if the process is running or the image is frozen. I'm now opening a Morphic world side by side with the GT/Lepiter GUI, to track in more details what is happening, but GT should provide improved visual feedback to its users about background running processes (like when a commit is happening, for example).

Have you tried to wrap your code in a [ ... ] fork?
I will. But that would not address the principle of least surprise regarding user experience. Other users would not start by forking a block and would they expect some GUI feedback about background running processes as happens with Jupyter or Elixir's LiveBook.
