switching light/dark mode doesn't give immediate feedback #109
Description
First of all, what a beautiful modern design, including logo. Really impressed with all different grid options & difficulty levels. Thanks for keeping it FOSS.
Bug is just me nit picking (just an excuse to show my gratitude). User doesn't get immediate feedback that dark/light mode has been changed. Ideally after switching modes, settings activity's mode should change instantaneously. But if it's complicated to solve , at least a toast or something.
