This is a really nice solution for STON, thank you! But in general terms, imagine I have some task and it’s not the trivial to add a progress bar. I could spawn a string morph and make circle the digits with some interval, but maybe there is something easier. For example Kommiter had a spinner morph that you could just open and it would be spinning. So when you run a task you can easily see that the task is still running
