- Consider a spinner animation affordance on anything that may run over 200ms.
- Set a minimum time for loading indicator display times so that animations won't look like a quick confusing flash in case timing runs slightly over 200ms. We recommend 400ms minimum display time.
Don't show a spinner animation if the wait time for the action will be less than 200ms. Any animation under 200ms can be seen as a quick flash and potentially confuse users.
