Onetastic with Dark Mode Support to Match OneNote Theme
Since Microsoft announced they are bringing OneNote Desktop app for Windows back to active development, they added dark mode support for those who prefer that to light backgrounds. This can be set under File > Options > General, choosing Black under Office Theme. Now Onetastic will follow this setting and will display its windows in Dark Mode. You will also notice that the icons are re-colored to look better in this mode. If you change your theme from dark to light or the other way around, you will need to restart OneNote for Onetastic to update its theme.
Here are some screenshots of Onetastic in dark mode:
Hope you enjoy the new dark theme support.
