In Copilot, if it is in the process of computing a completion, this icon in the bottom right corner will turn into a spinning circle. I can use this indicator to decide whether to wait for the completion to appear. Sometimes, when the circle stops spinning and no completion appears, I know that there’s no need to wait any longer and can continue manually editing my code. However, without this spinning circle, I wouldn’t be able to tell if it’s currently “computing a completion and I should wait” or “the computation has finished but there are no suggestions and I should continue modifying my code.”
