Yes, hiding the button could be a temporary workaround. On the other hand, I wonder how hard it would be to just kill the extension process from the main code.

This is not normally noticeable because extensions execute quickly. But for extensions that take a while-- i.e., those that you'd want to cancel --it turns out not to work. It appears to wait (possibly a very long time) for the extension to finish executing before stopping the operation. To replicate, select Extensions>Render>L-system. Set Order to 4. Click Apply, try to cancel the operation. If your computer is fast and that didn't take very long, set Order to 5, 6, or 7 to make the extension take longer to run.
